Area unit conversions
Area scales with the square of the linear unit. 1 m = 100 cm, but 1 m² = 10,000 cm². This non-obvious scaling is the most common source of area conversion errors.
- 1 m² = 10,000 cm² = 1,000,000 mm²
- 1 km² = 1,000,000 m²
- 1 hectare = 10,000 m²
- 1 acre = 4,047 m² ≈ 0.405 ha
Formula / How it works
All areas convert through square meters (m²).
