Converters · Added 9 August 2026
Convert an area between metric and imperial units, including the acre and hectare figures used in property and land listings.
Result
1 ft² in square metre

1 ft² = 0.09290304 m²
The same value in every unit

Area factors are the square of the length factors — a square foot is 0.3048² m², not 0.3048 m². Getting that wrong is the single most common conversion mistake in property listings.
How to use the area converter
- 1Enter the area figure you want to convert.
- 2Choose its unit and the unit you want. Metric and imperial units are listed separately.
- 3Read the result, with the same area shown in every unit below — helpful when a listing quotes square feet and the survey uses square metres.
- 4If you have a length rather than an area, use the length converter: area factors are squared and the two are not interchangeable.
Examples
A flat listed in square feet
- Input
- 1,200 square feet
- Result
- 111.483648 square metres
The rough rule that 1,000 sq ft is about 93 sq m gets you close enough to compare listings quickly.
Land in acres
- Input
- 2.5 acres
- Result
- 1.01171411 hectares
An acre is roughly 0.4 hectares, so acres to hectares is a division by about 2.47.
Flooring for a room
- Input
- 18 square metres
- Result
- 193.750388 square feet
About the area converter
Squared factors, and the mistake they cause
Every area unit is the square of a length unit, so its conversion factor is the length factor squared. A foot is 0.3048 metres, so a square foot is 0.3048² = 0.09290304 square metres. A yard is 0.9144 metres, so a square yard is 0.83612736 square metres.
Applying the unsquared factor is the most common error in area conversion, and it produces answers that are wrong by a factor of three or more without looking obviously absurd. A quick sanity check helps: a square metre is always about 10.8 square feet, so the square-foot figure should be roughly eleven times the square-metre one.
Property, land and materials
Property listings are where most people meet area conversions. Floor area in India and the US is quoted in square feet; most of Europe uses square metres. Comparing two listings across that divide means converting, and the difference between 100 sq m and 100 sq ft is enormous — one is a family flat, the other a small bedroom.
Materials are the other common case. Flooring, tiles, turf and paint are sold by coverage area, often in units that do not match the ones on your plan. Convert the room and the product to the same unit before dividing, and add an allowance for cuts and waste on top.
