How to convert hectares to square meters
Area factors are squared length factors. Acres here use international feet, not historical US survey feet.
Use x for the value in ha, b for the intermediate value in m², and y for the result in m².
m² = ha × 10000
Worked examples
10 ha ≈ 100000 m²
Step 1: (10 × 10000) ≈ 100000 m².
Step 2: 100000 ÷ 1 ≈ 100000 m².20 ha ≈ 200000 m²
Step 1: (20 × 10000) ≈ 200000 m².
Step 2: 200000 ÷ 1 ≈ 200000 m².
Results are rounded to 12 significant digits. Converting units does not increase the precision of the original measurement. Very large or small values outside JavaScript’s finite numeric range are rejected.
About Hectares
Hectares (ha) measures area under the conventions above. The base value in m² is (x × 10000), where x is the numerical value in ha. Factors shown here are rounded for display; calculations use the stored factor.
About Square meters
Square meters (m²) measures area under the conventions above. The base value in m² is (x × 1), where x is the numerical value in m². Factors shown here are rounded for display; calculations use the stored factor.
