How the area converter works
Last updated 10 November 2026
This converter uses exact definitions of each unit, so results are as accurate as the number you enter.
How it works
- Each unit is a fixed number of square metres.
Worked example
With the starting figures:
- 1.0000 ha is 2.471054 acre.
Where area units come up in South Africa
Property listings, title deeds, municipal plans and farm sales all use area, but not always in the same unit. A stand may be given in square metres, a smallholding in hectares, and an imported plan in acres or square feet. This converter lets you move between the units without hunting for a conversion table.
- Stand and erf sizes on property listings and rates accounts
- Floor area of a flat, office or shop when comparing rental per square metre
- Land and farm sizes, usually in hectares
- Imported products and plans that use square feet or acres
How to use it
Type the amount, choose the unit you have and the unit you want. The main answer appears at the top. The table below it shows the same amount in every other unit, which is handy when a form asks for a unit you did not expect.
Why the answers are exact
Every unit is defined as a fixed number of square metres, and the calculator multiplies by that number and then divides by the number for the unit you want. There is no rounding inside the sum. The display shows a limited number of decimals, but the figure behind it is the full value, so converting there and back returns what you started with.
Common mix-ups
- A hectare is a square with sides of one hundred metres, which is ten thousand square metres. It is not one hundred square metres.
- A square kilometre is much bigger than a hectare. Mixing them up changes the answer a hundredfold.
- Square feet and feet are different things. A room that is ten feet by ten feet is one hundred square feet.
- Areas do not scale like lengths. Doubling each side of a plot makes it four times as big.
What this does not cover
The converter turns one unit into another. It does not measure a plot, work out usable floor area or say what an official document counts as the stand size. For a price per square metre, divide the price by the converted area yourself.
A quick worked idea
Say a listing gives a stand in square metres and your plan is in hectares. Enter the amount, pick square metres as the unit you have and hectares as the unit you want. The answer is a small fraction of a hectare. The table underneath also shows acres and square feet, so you can compare with an overseas listing without a second trip to the converter.

Things to watch
- Property sizes in South Africa are normally given in square metres or hectares.
The conversion factors are definitions, not measurements. They are listed with their source in the data notes. Nothing you enter is stored or sent.
