Length & Area Converter
Convert length and area between metric and imperial units: metres, feet, miles, square metres, square feet, hectares, acres and dunams.
How it's calculated
Every unit is converted through one base unit: the metre for length and the square metre for area. The factors are exact definitions:
- 1 inch = 0.0254 m, 1 foot = 0.3048 m, 1 yard = 0.9144 m, 1 mile = 1,609.344 m, 1 nautical mile = 1,852 m.
- 1 square foot = 0.09290304 m², 1 acre = 4,046.8564224 m², 1 hectare = 10,000 m², 1 dunam = 1,000 m².
The value is multiplied by the factor of the unit you convert from and divided by the factor of the unit you convert to. Results are rounded to 12 significant figures.
