How big is a decimal of land in Uganda? One decimal is one-hundredth of an acre, which is about 40.47 square metres (m²) or roughly 436 square feet. A standard 50x100ft plot measures 5,000 square feet, which works out to about 11.5 decimals. In day-to-day property sales across Kampala, Wakiso, Mukono and Entebbe, this plot is almost always advertised as a 12-decimal plot.

If you have ever scrolled through land listings in Uganda and wondered what “12 decimals”, “25 decimals” or “50 decimals” actually means on the ground, this guide is for you. Below you will find simple, accurate answers to the questions Ugandan land buyers search for most: how many decimals are in a 50x100ft plot, a 100x100ft plot, a half acre and a full acre, plus conversion tables, worked examples, buying tips and answers to frequently asked questions.

What Is a Decimal of Land in Uganda?

In Uganda, land is commonly measured and sold in decimals, acres, hectares and square metres. Among ordinary buyers and sellers, the decimal is the most popular unit for residential plots, especially in Kampala and the surrounding Wakiso and Mukono areas.

A decimal is simply 1/100 of an acre. That is why one acre equals exactly 100 decimals. The conversions come from the acre itself:

• 1 acre = 43,560 square feet = 4,046.86 square metres
• 1 decimal = 43,560 ÷ 100 = 435.6 square feet
• 1 decimal = 4,046.86 ÷ 100 = 40.47 square metres

Because the decimal is tied directly to the acre, every decimal conversion is easy once you remember one number: 1 decimal = 40.47 m². Multiply the number of decimals by 40.47 to get square metres, or by 435.6 to get square feet.

Decimal to Square Metres and Square Feet Table

Decimals	Square Metres (m²)	Square Feet (sq ft)
1 decimal	40.47	436
5 decimals	202.35	2,178
6 decimals	242.81	2,614
10 decimals	404.69	4,356
12 decimals	485.62	5,227
15 decimals	607.03	6,534
20 decimals	809.37	8,712
25 decimals	1,011.71	10,890
30 decimals	1,214.06	13,068
50 decimals	2,023.43	21,780
75 decimals	3,035.14	32,670
100 decimals (1 acre)	4,046.86	43,560

How Many Decimals Make Up a 50 by 100 Feet Plot in Uganda?

This is the single most searched land-size question in Uganda, and for good reason. The 50x100ft plot is the classic residential plot size in Kampala and its suburbs. It is large enough for a comfortable family home with a compound, yet small enough to remain affordable for first-time land buyers.

The Maths Behind 50x100ft

1. Multiply the two sides: 50 ft × 100 ft = 5,000 square feet.
2. Divide by the size of one decimal: 5,000 ÷ 435.6 = 11.48 decimals.
3. In metric terms: 15.24 m × 30.48 m = 464.5 m², and 464.5 ÷ 40.47 = 11.48 decimals.

So a 50x100ft plot is about 11.5 decimals.

Why Is a 50x100ft Plot Sold as 12 Decimals?

You will notice that Ugandan listings rarely say “11.5 decimals”. Instead, they say “12 decimals (50x100ft)”. There are practical reasons for this:

• Rounding for simplicity. Sellers, brokers and surveyors round 11.48 up to a whole number, and 12 is the natural round-off.
• Survey margins. When a larger piece of land is subdivided, surveyors often allow a little extra so every plot reaches the standard size once boundaries are marked.
• Market habit. Buyers and sellers have used “12 decimals” as shorthand for a 50x100ft plot for years, so the expression stuck.

In square metres, 12 decimals equals 485.62 m², while a perfect 50x100ft rectangle is 464.5 m². The difference is only about 21 m², which is small, but it is worth knowing about so you can ask the right questions and measure your own plot.

You can see this convention in many real listings. For example, these 12-decimal plots (50x100ft each) in Gayaza Kiwenda and this 12-decimal titled plot in Namugongo Nabusugwe both use the 50x100ft description. The plots in Kasangati Kiti follow the same pattern.

What Can You Build on a 50x100ft Plot?

A 12-decimal plot gives you around 465 to 485 square metres. That is enough for:

• A 3 or 4 bedroom bungalow with a front garden, parking and a back yard
• A modest two-storey family home with servant quarters
• A small block of rental units, depending on your layout and budget
• A home with a boundary wall, gate, water tank and room for future extensions

Because plots like this are popular for family homes, they also tend to be easier to resell. Many buyers in areas such as Kira, Namugongo, Gayaza, Kasangati and Kyanja specifically search for 12-decimal plots, which keeps demand steady.

Common Mistake: Treating 50x100ft as 50 Decimals

Some first-time buyers confuse the numbers “50×100” and “50 decimals”. They are completely different. A 50x100ft plot is only about 12 decimals. A 50-decimal plot is a half acre, which is more than four times larger. Always confirm whether a seller is quoting the dimensions in feet or the area in decimals.

How Many Decimals Are in a 100x100ft Plot?

A 100x100ft plot is exactly twice the size of a 50x100ft plot.

1. 100 ft × 100 ft = 10,000 square feet
2. 10,000 ÷ 435.6 = 22.96 decimals
3. In metric: 30.48 m × 30.48 m = 929 m²

So a 100x100ft plot is mathematically about 23 decimals. In the Ugandan market, however, you will often see 100x100ft plots advertised as 25 decimals or even slightly above. The reason is the same as with the 12-decimal plot: rounding and survey margins. A true 25-decimal plot is a quarter acre, which is 1,011.71 m², or 10,890 square feet. That is roughly 104 ft by 104 ft, so a “100x100ft” plot sold as 25 decimals is really a little bigger than a perfect 100×100 square.

Real examples include this 25-decimal titled plot (100x100ft) in Ssisa along Entebbe Road and this 26-decimal plot (100x100ft) in Kitende.

Tip: when a listing says “100x100ft”, check whether the title shows 23, 24 or 25 decimals. A good seller will happily explain the exact measurement, and a proper boundary survey will confirm it.

How Many Decimals Are in a Half Acre in Uganda?

A half acre is 50 decimals. The numbers are clean because the decimal is defined as one-hundredth of an acre:

• 0.5 acre × 100 = 50 decimals
• 0.5 acre = 21,780 square feet
• 0.5 acre = 2,023.43 square metres
• 0.5 acre = about 0.2 hectare

If the half acre were a perfect square, each side would be about 45 metres (roughly 148 feet). In reality, plots come in many shapes, so you might see 100x218ft or 150x145ft, both of which give approximately a half acre.

A half acre is a popular size for buyers who want a large family home with a big compound, a small gated estate, a school or clinic site, or space to build several rental units. If you want to see how half-acre land is presented in real listings, look at this half acre in Kawuku Bwerenga along Entebbe Road and this 50-decimal plot in Kyanja Kungu.

A half acre can also be subdivided. As a rough guide, four 12-decimal plots add up to 48 decimals, which fits inside a half acre with a little left over for an access path.

How Many Decimals Are in a Full Acre in Uganda?

An acre is 100 decimals. That is the starting point for every other conversion in this guide.

• 1 acre = 100 decimals
• 1 acre = 43,560 square feet
• 1 acre = 4,046.86 square metres
• 1 acre = 0.4047 hectare

A square acre has sides of about 63.6 metres (roughly 209 feet). Again, real acres come in many shapes, such as a long rectangle of 100ft by 435.6ft.

For subdivision, one acre can produce eight 12-decimal plots (96 decimals) on paper, leaving around 4 decimals for paths. Once developers add proper access roads and drainage, the final number of sellable plots is often lower, so always ask how many plots a layout actually delivers. You can see how acre-sized land is described in listings such as this acre of land in Kira Kiwologoma and this 1 acre in Kawempe Mpererwe.

Other Common Plot Sizes in Uganda and Their Decimals

Not every plot is 50x100ft or 100x100ft. Here are other sizes you will meet when searching for land in Kampala, Wakiso, Mukono and Entebbe:

Plot Size (ft)	Area (sq ft)	Approx. Decimals	Area (m²)
25×50	1,250	2.9	116.1
40×80	3,200	7.4	297.3
50×50	2,500	5.7	232.3
50×100	5,000	11.5	464.5
60×100	6,000	13.8	557.4
70×100	7,000	16.1	650.3
75×100	7,500	17.2	696.8
80×100	8,000	18.4	743.2
100×100	10,000	23.0	929.0
100×150	15,000	34.4	1,393.5
100×200	20,000	45.9	1,858.1
150×150	22,500	51.7	2,090.3

For plots such as 15, 20, 24 or 30 decimals, which are very common in listings around Kira, Najjera, Ntinda, Kyanja and Bwebajja, simply multiply the decimals by 435.6 to find the area in square feet, then compare it with the dimensions of the land you are viewing.

How to Convert Decimals in Uganda: Simple Formulas

You do not need a calculator app to work out land sizes. Use these formulas:

• Square feet to decimals: divide the area in square feet by 435.6
• Square metres to decimals: divide the area in square metres by 40.47
• Decimals to square metres: multiply decimals by 40.47
• Decimals to square feet: multiply decimals by 435.6
• Decimals to acres: divide decimals by 100
• Acres to decimals: multiply acres by 100
• Hectares to decimals: multiply hectares by 247.1

Worked Examples

Example 1: A plot measures 60ft by 100ft. Area = 6,000 sq ft. Decimals = 6,000 ÷ 435.6 = about 13.8 decimals. It would typically be sold as a 14-decimal plot.

Example 2: A title says the plot is 700 square metres. Decimals = 700 ÷ 40.47 = about 17.3 decimals.

Example 3: A seller offers 35 decimals. Area = 35 × 435.6 = 15,246 sq ft, or 35 × 40.47 = 1,416.5 m². In acres, that is 0.35 acre.

Example 4: You want exactly 20 decimals. That is 8,712 sq ft or 809.4 m², about 80ft by 109ft.

Why Plot Sizes on Paper Sometimes Differ from the Ground

Many Ugandan buyers worry when the measured area does not match the advertised figure exactly. Small differences are common and usually have simple explanations:

• Rounding. 11.48 decimals becomes 12, and 22.96 becomes 23 or 25.
• Irregular shapes. Not every plot is a perfect rectangle. Slanted boundaries and curved road frontages change the area.
• Access allowances. Large land that is subdivided loses some space to paths and roads, so individual plots may be slightly smaller or larger than advertised.
• Old survey methods. Older land records may use different measuring techniques than modern GPS equipment.
• Sloping land. Hilly areas, which are common across Kampala, can feel larger or smaller than the flat measurement.

The best protection is to hire a licensed surveyor to confirm boundaries and area before you pay in full. The cost is small compared with the value of the land.

Plot Sizes in Popular Areas Around Kampala

Different neighbourhoods tend to favour different plot sizes, and knowing what is common helps you set realistic expectations before you start viewing land.

Kira, Namugongo and Najjera. These fast-growing northeastern suburbs are full of 12-decimal and 15-decimal plots, ideal for family homes. Our area guides explain each neighbourhood in detail: the Kira real estate guide, the Namugongo real estate guide and the Najjera guide.

Gayaza and Kasangati. Along the Gayaza and Bombo road corridors, buyers often find 12-decimal plots as well as larger 25-decimal, half-acre and acre pieces. Read the Gayaza real estate guide to understand which parts of Gayaza suit which budgets.

Kyanja, Kiwatule and Kisaasi. Closer to the city, plots tend to be smaller and more expensive per decimal. The Kyanja guide, Kiwatule guide and Kisaasi guide show what each area offers.

Entebbe Road corridor. Seguku, Kitende, Bwebajja, Garuga and Kawuku are well known for 12-decimal, 25-decimal and half-acre plots. See the Seguku guide, Bwebajja buyers guide, Garuga guide and Kawuku guide.

Munyonyo and Kigo. Lake-view plots here can be priced very differently from inland plots even when the decimals are identical, which is why location matters as much as size. The Munyonyo and Kigo guide covers the details.

Bigger Land in Uganda: Acres, Hectares and Square Miles

Outside the city, land is often measured in larger units. Here is how they compare with decimals:

Unit	In Decimals	In Acres	In m²
1 acre	100	1	4,046.86
1 hectare	247.1	2.471	10,000
5 acres	500	5	20,234
10 acres	1,000	10	40,469
1 square mile	64,000	640	2,589,988

Farmland and large investment parcels are typically quoted in acres or square miles. For example, you may see 3 square miles of farmland in Nakaseke or 7 square miles in Kayunga. Mid-sized pieces such as 10 acres on Mityana Road or 9.5 acres of lake-view land in Mukono Nkokonjeru sit in between. When you compare prices, convert everything to the same unit first. Price per decimal is the fairest yardstick.

How to Compare Land Prices Using Decimals

Decimals make it easy to compare plots of different sizes. The method is simple:

1. Take the total asking price of the plot.
2. Divide it by the number of decimals.
3. Compare the resulting price per decimal with other plots in the same area.

Always compare plots in the same neighbourhood and with the same type of title, road access and utilities. A plot beside a tarmac road with water and electricity will naturally cost more per decimal than one deep inside a village with only a murram access path, even if both are exactly 12 decimals.

Buyer Checklist Before You Pay for Land in Uganda

Knowing the size is only the first step. Before you commit your money, work through this checklist:

1. Confirm the size in decimals, feet and square metres. Ask the seller for all three and check they agree.
2. Inspect the land title. Check that the plot area on the title matches the seller’s claim.
3. Understand the tenure. Mailo, freehold and leasehold land come with different rights and conditions, so learn how each works before buying.
4. Verify the seller. Make sure the person selling is the registered owner or is properly authorised.
5. Hire a licensed surveyor. Have boundaries opened, confirmed and marked with boundary stones.
6. Visit the plot yourself. Walk the boundaries, check access, drainage, slope and neighbouring buildings.
7. Check road and utility access. Confirm there is a clear access road plus water and electricity nearby.
8. Use a lawyer for the transfer. Have the sale agreement and title transfer handled properly.
9. Keep every receipt and document. Record each payment in writing.

If you are new to the process, the guide on land tenure systems in Uganda and the buying process posts on this site explain these steps in more detail.

Common Land Size Mistakes to Avoid

• Mixing up feet and decimals. “50×100” is a shape in feet, not a number of decimals.
• Assuming all 12-decimal plots have the same shape. A 12-decimal plot can be 50x100ft, but it can also be 40x130ft or 60x87ft. Shape affects how you can build.
• Ignoring the road. A plot with a narrow frontage and a long body is harder to design for than a wider plot of the same decimals.
• Buying without measuring. Never rely only on a verbal description. Measure the land or have it surveyed.
• Forgetting future needs. If you plan to add rentals or extensions, consider a plot bigger than your first house needs.
