Area Converter
Convert area among mm², cm², m², ha, km², in², ft², and acres.
How to use
- Enter an already-known area and select its current area unit and the destination such as m², ha, or acre.
Capabilities and scope
Area is a squared dimension, so it cannot use a simple linear length factor. This tool normalizes land and drawing areas through square meters.
How it works
Each unit stores the number of square meters in one unit. For example, 1 ha = 10,000 m² and 1 acre = 4046.8564224 m².
Example
1 hectare is 10,000 m², or about 2.47105 acres.
Useful for
- Compare hectares and acres for land
- Convert architectural areas between ft² and m²
- Express small areas in cm² or mm²
Before you use it
- It does not calculate the area of a shape; it only changes the unit of an already known area value.

Frequently asked questions
Can I reuse a meter-to-foot factor for area?
No. Area is squared, so m²-to-ft² requires the corresponding area factor.
