Formula

1 m² = 0.0001 ha

hectares = square meters × 0.0001 — reverse: square meters = hectares × 10000

The factor is derived from the SI definitions of both units (base unit: m2) as listed in NIST SP 811; results on this page are shown to 6 significant figures, the API returns up to 12.

Worked examples

5 m² = 0.0005 ha
12.5 m² = 0.00125 ha
100 m² = 0.01 ha

FAQ

How many hectares are in one square meter?

1 m² = 0.0001 ha. The factor comes from the SI definitions of both units (NIST SP 811 / BIPM), so it is exact or correct to at least 10 significant figures.

What is the formula to convert square meters to hectares?

Multiply the value in square meters by 0.0001: hectares = square meters × 0.0001. For example, 5 m² = 0.0005 ha.

How do I convert hectares back to square meters?

Multiply by the inverse factor 10000 (square meters = hectares × 10000), or use the hectares-to-square meters page.
