Area Units Guide
Convert between square meters, square feet, acres, and hectares — essential for real estate and land measurement
Overview
Area measures the size of a two-dimensional surface. Common units include square meters (m²) and square feet (ft²) for smaller spaces, and hectares and acres for land measurement.
Understanding area units is essential for real estate, construction, agriculture, and interior design.

Quick Conversion Tips
m² ↔ ft²
Multiply m² by 10.764 to get ft²
Multiply ft² by 0.093 to get m²
Acre ↔ Hectare
1 hectare ≈ 2.47 acres
1 acre ≈ 0.4 hectares
Quick Estimate
10 ft² ≈ 1 m²
2.5 acres ≈ 1 hectare
Remember
Area units are squared
1 m = 3.28 ft, but 1 m² = 10.76 ft²
