About the Area Converter
This converts an area between metric and imperial units — the tool you need for land and property. Convert a plot from acres to hectares or square metres, a room or floor area between square metres and square feet, or a large parcel between square kilometres and square miles. Enter a value, choose the units, and it converts instantly.
How it works
Each unit is defined by an exact factor relative to the square metre; your value is converted to square metres and then to the target unit. Useful reference points:
- 1 hectare = 10,000 m² (a square 100 m on each side).
- 1 acre = 4046.8564 m² (about 0.405 hectares, or roughly 40% of a hectare).
- 1 square foot = 0.092903 m², and 1 square yard = 9 square feet.
Note that area factors are the square of length factors — a square foot is 0.3048² m², not 0.3048 m².
Assumptions and behaviour
- Uses the international acre (4046.8564224 m²); the tiny "US survey acre" difference isn't applied.
- Acres and hectares are the common land-area units — 1 hectare ≈ 2.471 acres.
- Results show about 7 significant figures.
- The Swap button reverses the two units.
Limitations
- It converts area only. Don't confuse it with length: converting the sides of a shape is a length conversion, while its surface is an area conversion.
- It gives a numeric area conversion; it doesn't calculate the area of a shape from its dimensions (use a geometry/area calculator for that).
- Displayed values are rounded, so hand-chaining rounded figures can drift slightly.
Privacy
The conversion runs entirely in your browser. Nothing is uploaded or stored.
