How Area Conversions Work
Area units are derived from the square of linear dimensions. The base unit in the International System of Units (SI) is the square meter (m²). Because area scales quadratically, conversion ratios are the square of their linear counterparts:
Land Measurements: Acres and Hectares
The International Acre (ac)
Defined historically as 1 furlong by 1 chain (660 ft × 66 ft), the modern international acre equals exactly 43,560 square feet or 4,046.8564224 m².
The Hectare (ha)
The non-SI metric unit accepted for use with the SI is defined as the area of a square with 100-meter sides (100 m × 100 m = 10,000 m²). One hectare is approximately 2.471 acres.
Exact Area Conversion Standards
| Unit | Symbol | System | Exact Definition in m² |
|---|---|---|---|
| Square Foot | sq ft | Imperial / US | 0.09290304 m² |
| Acre | ac | Imperial / US | 4,046.8564224 m² |
| Hectare | ha | Metric | 10,000 m² |
| Square Kilometer | km² | Metric SI | 1,000,000 m² |
| Square Mile | sq mi | Imperial / US | 2,589,988.110336 m² (640 ac) |
| Square Centimeter | cm² | Metric SI | 0.0001 m² |
Common Worked Examples
Example 1: Convert 100 Square Meters to Square Feet
100 ÷ 0.09290304 = 1,076.391042 sq ft.
Example 2: Convert 5 Hectares to Acres
50,000 m² ÷ 4,046.8564224 m²/ac = 12.355269 acres.
