What is an Area Converter?
An area converter converts a surface measurement between metric and traditional units — square millimetres, square centimetres, square metres, square kilometres, acres, hectares, square feet, and square yards. Indian real estate listings almost always quote apartment carpet or built-up area in square feet, while agricultural land is measured in acres or hectares, and land records in several states still reference older local units. Buyers comparing a "1,200 sq ft" flat with a builder's brochure in square metres, farmers converting hectares to acres for a loan application, or students solving mensuration problems all need quick, accurate area conversion.
Conversion Formula
Every unit is converted to square metres first (the base unit), then divided by the target unit's square-metre equivalent:
Result = value in m² ÷ (target unit factor)
Common Conversion Factors
| Unit | Equal to (m²) |
|---|---|
| Square millimetre (mm²) | 0.000001 m² |
| Square centimetre (cm²) | 0.0001 m² |
| Square metre (m²) | 1 m² (base unit) |
| Square kilometre (km²) | 1,000,000 m² |
| Acre | 4,046.86 m² |
| Hectare | 10,000 m² |
| Square foot (sq ft) | 0.0929 m² |
| Square yard (sq yd) | 0.836127 m² |
Worked Example
A flat listed at 1,200 sq ft — what is that in square metres?
Now compare a 2-acre farm plot to hectares: 2 × 4,046.86 = 8,093.72 m², then 8,093.72 ÷ 10,000 = 0.809372 hectares — roughly 0.81 hectares, a conversion farmers frequently need for subsidy or loan paperwork.
