Guides
The Area Converter turns a single area measurement into its equivalent across 15 units at once. Enter one value, choose the unit it is expressed in, and the tool instantly builds a table showing the same area in square meters, hectares, acres, square feet, square miles, and more.
Land, real estate, and construction all measure area differently depending on region and industry: metric countries use square meters and hectares, US real estate uses square feet and acres, and large tracts are often described in square miles or square kilometers. This tool bridges all of them at once.
How to use it
- Type the amount you want to convert into the Amount box.
- Pick the unit that amount is in from the Unit list.
- Optionally set the Decimal precision (0 to 10 places) for how the results are rounded.
The results table updates automatically. Very large or very small results (square nanometers, square kilometers) are shown in scientific notation so nothing is lost to rounding. Use the copy and download buttons to grab every conversion as CSV.
How many square feet are in an acre?
One acre equals 43,560 square feet exactly. This tool computes that conversion (and every other unit) instantly.
What is the difference between a hectare and an acre?
A hectare is exactly 10,000 square meters (a square 100 m on each side) and is the standard metric unit for land area. An acre is an older imperial unit equal to about 4,047 square meters — roughly 2.47 acres per hectare.
Are hectare and square hectometer the same thing?
Yes — a hectare is by definition a square hectometer (100 m × 100 m = 10,000 m²). Both names are listed here because "hectare" is the common term while "square hectometer" completes the metric square-unit ladder (m², dam², hm², km²).
How do I convert square meters to square feet?
Multiply square meters by about 10.7639 to get square feet. This tool applies that factor (and its inverse) automatically.
