📐 How to Use

  1. Choose the unit your measurement is in from the From dropdown, such as Square Meter, and key the figure into the input under it.
  2. Choose the unit you need from the To dropdown; the converted area appears immediately in the result panel as you change either side.
  3. Tap the swap button in the middle to flip the pair, which also carries the current result across into the input box.
  4. Copy the figure with the Copy button, start from a card in the Common Area Conversions grid, or follow a link in the All Area Conversions list to a dedicated page with a conversion table.

❓ Frequently Asked Questions

QHow many square feet are in a square meter?
A square meter is 10.7639 square feet. The figure is the square of the length conversion: a foot is 0.3048 meters, 0.3048 squared is 0.092903, so a square foot covers 0.092903 square meters and one divided by that gives 10.7639.
QHow many acres are in a hectare?
One hectare is 2.471052 acres, and one acre is 0.404686 hectares. The hectare is defined as 10,000 square meters. The acre is 4,046.86 square meters, equal to 4,840 square yards or 43,560 square feet, a holdover from furlong and chain field measure.
QWhy is a square kilometer a million square meters?
Because area grows with the square of length: a kilometer is 1,000 meters and 1,000 squared is 1,000,000. The same rule makes one square kilometer 100 hectares and 0.38610216 square miles. Forgetting to square the ratio is the most common error in area work.
QWhy does 1 square foot convert to 143.9999 square inches?
A square foot is exactly 144 square inches by definition. The stored square foot factor, 0.092903 square meters, is rounded from 0.09290304, and that shows up in the eighth significant digit of the answer. It is far below the precision of any measured area.

ℹ️ About Area Conversion

Area is length squared, and the squaring is what makes its conversions counterintuitive: double a length and the area quadruples. A foot is 0.3048 meters, so a square foot is 0.3048 squared, or 0.092903 square meters. Land measure adds its own history on top. A hectare is a tidy 10,000 square meters, a square 100 meters on each side, while the acre began as the ground a team of oxen could plow in a day and settled at 4,046.86 square meters, which is 43,560 square feet.

Ten units are available, running from square millimeters up to square miles and including hectares and acres. The square meter is the base: your figure is multiplied by its unit's area in square meters, then divided by the target unit's. Results of 10 or more are rounded to four decimals, smaller ones to six or eight. Calculation is done in your browser.
