Enter a value. Your answer appears below.

Choose the unit you have in “From” and the unit you need in “To”. No calculate button needed.

Area measures a surface, such as a room or a plot of land. Acres here use the international foot, not the historical US survey foot.

Numbers only. For example, 12.5 or 1e6 (one million).

Example: 1 hectare = 10,000 square meters. Results show up to 15 significant digits. Very large or small answers may use e notation: 1e6 means 1,000,000. Numbers are processed only in this browser.

How to use Area Converter

  1. Enter an area rather than just a side length.
  2. Choose the current area unit, such as acres, and the desired unit, such as square meters.
  3. Read or copy the automatically updated result; use Swap to reverse the comparison.

A closer look

Area describes the size of a surface. Because both dimensions change, area factors are the square of length factors: 1 meter is 100 centimeters, but 1 square meter is 10,000 square centimeters. One hectare is 10,000 square meters. The international acre used here is exactly 4,046.8564224 square meters, based on 43,560 international square feet. Historical US survey acres use a slightly different definition.

A practical example

One hectare equals 10,000 square meters. To convert a rectangular plot, first calculate its area; this tool converts area units, not side lengths.

A useful tip

For a rectangular room, multiply its length by its width first, using the same length unit for both. Then convert the resulting square units.

Good questions. Simple answers.

Can I convert meters directly into square meters?

No. A length alone does not tell you a surface area. You need the shape and its other dimensions.

What is the difference between an acre and a hectare?

They are different area units. One hectare is about 2.47105381467 international acres.
