About Area Converter
An area converter changes a measurement from one area unit to another — for example square meters to square feet, or acres to hectares — while keeping the physical size the same. This tool converts between nine units (square meters, square kilometers, square feet, square yards, square miles, acres, hectares, square inches and square centimeters) using exact, internationally agreed factors, so the numbers match surveying and legal standards rather than rounded approximations.
Area units split into two families. The metric (SI) family scales in powers of ten: 1 square meter = 10,000 square centimeters, 1 hectare = 10,000 square meters, and 1 square kilometer = 1,000,000 square meters. The imperial and US customary family is built on the international foot: 1 square foot = 0.09290304 m² exactly, 1 square yard = 0.83612736 m², and 1 square mile = 2,589,988.110336 m². Because both families ultimately reference the meter (1 foot = 0.3048 m by definition), every conversion here routes through square meters as a common base, which keeps results consistent in both directions.
A few conversions come up constantly. One acre equals 43,560 square feet, which works out to 4,046.8564224 m² — roughly 0.405 hectares. One hectare is exactly 10,000 m², or about 2.471 acres, which is why farmland and land parcels are often quoted in both. For buildings, 1 square meter ≈ 10.7639 square feet, and 1 square foot ≈ 0.0929 square meters.
Which unit you reach for depends on the job. Real estate listings use square feet in the US and UK and square meters across most of Europe and Asia to describe floor area. Farmland, forestry and large land sales use acres (US, UK) or hectares (most other countries). Construction, flooring and tiling work in square meters, square feet or square yards. Very small areas — a sensor, a circuit board, a material sample — are measured in square inches or square centimeters, while regional and geographic areas use square kilometers or square miles.
To use the converter, enter a number, choose the unit you have and the unit you want, and the result updates instantly. Tick "Show all units" to see the same area expressed in all nine units at once — handy when you need to compare a plot in acres, hectares and square meters side by side. Every factor used here is an exact value, not a rounded shortcut, so the results are safe to reuse in property listings, construction quotes and land surveys. Everything is calculated in your browser, so nothing is uploaded and there is no wait.
Frequently asked questions
- How many square feet are in a square meter?
- One square meter equals about 10.7639 square feet. The exact relationship comes from 1 square foot = 0.09290304 m², so 1 m² = 1 / 0.09290304 ≈ 10.7639 ft². To go the other way, multiply square feet by 0.0929 to get square meters.
- How do I convert acres to hectares?
- Multiply the number of acres by 0.404686 to get hectares, since 1 acre = 4,046.8564224 m² and 1 hectare = 10,000 m². To convert hectares back to acres, multiply by 2.471054. For example, 5 acres ≈ 2.0234 hectares.
- How big is one acre?
- One acre is 43,560 square feet, which is exactly 4,046.8564224 square meters or about 0.4047 hectares. For a mental picture, an acre is a little smaller than an American football field including its end zones (that full field is about 1.32 acres).
- What is the difference between metric and imperial area units?
- Metric (SI) units — square centimeters, square meters, hectares and square kilometers — scale in powers of ten, so conversions are clean multiples of 10. Imperial and US customary units — square inches, square feet, square yards, acres and square miles — are based on the foot and yard and use fixed historical factors instead.
- Which area units are used in real estate?
- Homes and floor plans are usually quoted in square feet in the US and UK and in square meters across most of Europe and Asia. Land, plots and farmland are measured in acres in the US and UK and in hectares in most other countries, so listings often show both.
