What this area converter does
This area converter converts areas between square millimetres, square centimetres, square metres, hectares, square kilometres, square feet, and acres. Enter a value, pick its current unit and the unit you need, and read the converted area. It is built for land, property, rooms, and plots, where listings and plans routinely mix metric and imperial measures between different countries and professions.
The relationships behind the conversion
One hectare is exactly 10,000 square metres, and one acre is 43,560 square feet. Those fixed relationships are why a plot described in acres needs care when compared with a metric listing: the numbers differ by large factors, and a small misunderstanding at this scale becomes a big difference in real space, price per unit, or materials ordered.
Good to know
Conversions use exact defined factors and results are rounded to six decimal places. The converter changes units only; it does not measure areas from dimensions or maps, so for a rectangular space you still need to multiply length by width first.
Frequently asked questions
How many square metres are in a hectare?
Exactly 10,000. A hectare is defined as a square 100 metres on each side, so converting hectares to square metres simply multiplies by 10,000, and the reverse divides by the same factor.
How do I convert acres to square feet?
Enter the acre value and convert from acres to square feet; one acre equals 43,560 square feet. The tool applies that defined factor and rounds the result to six decimal places.
Can this measure the area of my room?
Not directly. The converter changes one area unit into another; it does not calculate area from measurements. Work out the area in any unit first, then convert it here if you need different units.
