About this calculator
An area converter changes a surface measurement between metric units (square meter, hectare, square kilometer), imperial/US units (square inch, foot, yard, mile) and the acre and are used for land. Values convert through the square meter as a common base.
A key point is that area ratios are the square of the corresponding length ratios: because one meter is 3.28084 feet, one square meter is 3.28084² ≈ 10.7639 square feet. The land units are fixed too: one acre is 43,560 square feet ≈ 4,046.86 m², and one hectare is exactly 10,000 m².
Worked example: to convert 50 square meters to square feet, multiply by 10.7639, giving about 538 ft². To find how many acres a 20,000 m² plot covers, divide by 4,046.86, giving about 4.94 acres. The "all units" table shows the area in every unit at once, handy for real estate, flooring and farming.
Frequently asked questions
How many square feet are in a square meter?
One square meter equals about 10.7639 square feet. Note it is the square of the length ratio: because a meter is 3.28084 feet, a square meter is 3.28084² ft².
How big is an acre?
An acre is 43,560 square feet, or about 4,046.86 square meters. A hectare (10,000 square meters) is about 2.471 acres.
How many square meters in a hectare?
A hectare is exactly 10,000 square meters — a square 100 m on each side. It is the common metric unit for land area.
How many acres are in a hectare?
This area converter treats one hectare as about 2.471 acres, and one acre as about 0.4047 hectares. So a 10-hectare field is roughly 24.7 acres.
Why is a square meter more than three square feet?
Because area scales with the square of length. A meter is about 3.28 feet, so a square meter is 3.28² ≈ 10.76 square feet, not 3.28.
How big is an acre in real terms?
An acre is about 4,047 square meters, roughly the size of a standard football (soccer) pitch without the run-off, or about 60% of an American football field.
What is the difference between an are and an acre?
They sound alike but differ greatly: an are is 100 square meters, while an acre is about 4,047 square meters. A hectare is 100 ares.
