Area Conversion Formulas
Master area conversions with precise formulas and conversion factors for metric, imperial, and agricultural measurement systems.
1Basic Area Conversion Formula
⚠️ Important: Square the Linear Conversion Factor
Since area is two-dimensional, you must square the linear conversion factor.
Example: Convert 5 m² to ft²
Linear factor: 1 m = 3.28084 ft
Area factor:
Example: Convert 1000 ft² to m²
Linear factor: 1 ft = 0.3048 m
