📐 Free Area Converter

The Area Converter is a free online tool for converting land and surface areas between square meters (m²), square feet (ft²), square kilometers (km²), acres, and hectares (ha). It is ideal for real estate listings, land purchases, construction projects, gardening, and agriculture. The converter runs locally in your browser, so your measurements are never uploaded.

The converter uses the square meter as the base unit: 1 m² = 10.763910417 ft², 1 hectare = 10,000 m², 1 acre = 4046.8564224 m², and 1 km² = 1,000,000 m². Your input is converted to square meters first and then to the target unit, giving exact results for any unit pairing.

1. Enter the area value you want to convert.
2. Select the input unit (m², ft², km², acre, or hectare) in the first dropdown.
3. Select the target unit in the second dropdown and click Convert.
4. Read the converted area instantly, with the calculation shown below the result.

How big is an acre?

One acre equals 43,560 square feet or about 4046.86 square meters — roughly the size of an American football field. It remains the standard land unit in the US and the UK.

What is a hectare?

A hectare is exactly 10,000 square meters (100 m × 100 m). It is the standard metric unit for land area used in agriculture and real estate worldwide.

Is this area converter accurate?

Yes. The tool uses the exact official conversion factors, including the precise definition of the acre and the hectare, so results are reliable for legal and professional use.

For real estate, remember that 1 m² ≈ 10.76 ft², so a 100 m² apartment is roughly 1076 ft². For large land parcels, 1 hectare ≈ 2.47 acres.
