Plot sizes in Uganda are often quoted in decimals. If you are used to acres, hectares, meters or feet, it can get confusing. This guide gives you the exact conversion factors, simple formulas, and ready tables so you can price land correctly and avoid surprises on viewing day.
What is a “decimal” in Uganda?
A decimal is one one-hundredth of an acre.
- 1 decimal = 0.01 acre
- 1 acre = 100 decimals
Because most residential plots are smaller than an acre, sellers use decimals for clarity. Farmland and big parcels are usually quoted in acres or hectares.
Core conversions (bookmark these)
- 1 acre = 100 decimals = 4,046.856 m² = 43,560 ft² = 0.404686 ha
- 1 decimal = 40.4686 m² = 435.6 ft² = 0.00404686 ha
- 1 hectare = 2.47105 acres = 247.105 decimals = 10,000 m²
Rounding tip: For quick mental math, use 40.47 m² and 435.6 ft² per decimal. For contracts, use exact figures.

Common plot sizes in feet and their decimals
| Size (feet) | Area (ft²) | Decimals | m² (approx) |
|---|---|---|---|
| 50 × 100 | 5,000 | 11.48 | 464.5 |
| 60 × 100 | 6,000 | 13.77 | 557.4 |
| 70 × 100 | 7,000 | 16.08 | 650.3 |
| 80 × 100 | 8,000 | 18.36 | 743.2 |
| 100 × 100 | 10,000 | 22.96 | 929.0 |
| 50 × 70 | 3,500 | 8.03 | 325.2 |
Formula in feet:
Decimals = length ft×width ft435.6\dfrac{\text{length ft} \times \text{width ft}}{435.6}
Common plot sizes in meters and their decimals
| Size (m) | Area (m²) | Decimals |
|---|---|---|
| 15 × 30 | 450 | 11.13 |
| 20 × 25 | 500 | 12.36 |
| 20 × 30 | 600 | 14.83 |
| 25 × 30 | 750 | 18.54 |
| 30 × 30 | 900 | 22.24 |
Formula in meters:
Decimals = length m×width m40.4686\dfrac{\text{length m} \times \text{width m}}{40.4686}
Acres ↔ decimals ↔ hectares
| Acres | Decimals | Hectares |

Fast rules
- Multiply acres × 100 to get decimals
- Multiply hectares × 247.105 to get decimals
- Multiply decimals × 40.4686 to get m²
How to convert any plot yourself
1. Get the area
- Feet: length × width
- Meters: length × width
2. Convert to decimals
- From feet: divide by 435.6
- From meters: divide by 40.4686
3. Check the title and survey
- Compare your result to the survey map and title. If your on-ground size differs, ask a licensed surveyor to re-open beacons.
4. Price correctly
- If the seller quotes price per decimal, multiply that rate by your decimal figure.
- Add 5–12% to cover search, survey, legal and transfer
Examples you can copy
- 50 × 100 ft
Area = 5,000 ft²
Decimals = 5,000 ÷ 435.6 = 11.48
If price is UGX 30m per decimal, estimate = 11.48 × 30m = UGX 344.4m - 20 × 30 m
Area = 600 m²
Decimals = 600 ÷ 40.4686 = 14.83
At UGX 18m per decimal, estimate = 14.83 × 18m = UGX 266.9m
Mistakes that cost buyers money
- Relying on “50 × 100” without checking the map. Some plots exclude a road reserve or have irregular shapes.
- Confusing net and gross area. Estates sometimes quote gross before road or utility corridors.
- Ignoring slope. A steep site may need retaining walls that affect your total project cost even if the area is correct.
- Skipping beacon checks. Always have a licensed surveyor confirm beacons before payment.
- Pricing with the wrong unit. If the quote is per decimal and you computed per acre, the total will be wrong.
Turn numbers into action
When you see a plot you like, we will:
- Confirm the area against the survey map
- Run the title search for encumbrances
- Re-open beacons with a licensed surveyor
- Structure payments through a law firm
- Handle transfer and registration until you hold the title
