Converted to all area units
Tip: click any row to make that unit the input.
How It Works
Every unit is converted through square meters (m²), the SI unit of area, using exact internationally defined factors. Type a value, choose the unit you're starting from, and the list below updates live with the equivalent in all other units — no need to pick a "to" unit or press a button.
Example
1 hectare = 10,000 m² = 0.01 km² = 2.4711 acres = 107,639 ft²
Frequently Asked Questions
How do I convert between two specific units?
Enter your value, select the unit it's in from the "From unit" dropdown, and read the result off the row for the unit you want. Clicking a row makes that unit the new input, so you can chain conversions.
How many square meters are in a hectare and a square kilometer?
1 hectare = 10,000 m², and 1 km² = 1,000,000 m² = 100 hectares. Hectares are the standard metric unit for land area.
How big is an acre in metric units?
1 acre = 4,046.8564224 m² exactly, which is about 0.4047 hectares. Conversely, 1 hectare ≈ 2.4711 acres.
Are the conversion factors exact?
Yes. Imperial units are defined from the international foot (1 ft = 0.3048 m exactly), so 1 ft² = 0.09290304 m², 1 yd² = 0.83612736 m², and 1 mi² = 2,589,988.110336 m² are all exact values. Displayed results are rounded for readability.
Can it calculate the area of a room?
This tool converts between area units. To compute an area from length × width, use our Square Footage Calculator, then convert the result here.
