Square Meters to Hectares
Convert square meters (m²) to hectares (ha). Both measure surface measurement, and the conversion comes up in real estate, farming, construction work.
The Formula
``
hectares = square meters × 0.0001
square meters = hectares × 10000
`
One square meter is 1.0000e-4 hectares, and one hectare is 10,000 square meters.
Conversion Table
| Square Meters | Hectares |
|---|---|
| 1 m² | 1.0000e-4 ha |
| 2 m² | 2.0000e-4 ha |
| 5 m² | 5.0000e-4 ha |
| 10 m² | 0.001 ha |
| 25 m² | 0.0025 ha |
| 50 m² | 0.005 ha |
| 100 m² | 0.01 ha |
| 500 m² | 0.05 ha |
| 1,000 m² | 0.1 ha |
The Other Direction
| Hectares | Square Meters |
|---|---|
| 1 ha | 10,000 m² |
| 2 ha | 20,000 m² |
| 5 ha | 50,000 m² |
| 10 ha | 100,000 m² |
| 25 ha | 250,000 m² |
| 50 ha | 500,000 m² |
| 100 ha | 1,000,000 m² |
| 500 ha | 5,000,000 m² |
| 1,000 ha | 10,000,000 m² |
What Each Unit Is
Square Meters (m²) — the area of a square one metre on each side — the SI derived unit of area. The metric standard for floor area, land and materials.
Hectares (ha) — exactly 10,000 square metres, or a square 100 m on each side. The metric land unit, introduced with the metric system for agriculture and forestry.
A Sense of Scale
A parking space is about 12 m²- A small flat is 45 m²
- A tennis court is 261 m²
- A hectare is about 2.47 acres
- A rugby pitch is roughly 1 hectare
Precision
The factor 0.0001 is exact by international agreement, not a rounded approximation. Any imprecision in a result comes from your input, not the conversion.
In Code
`javascript
const squareMeterToHectare = (value) => value * 0.0001;

How Many Decimals Do You Need?
Rounding the factor costs accuracy, and how much depends on the factor. Converting 137 m² with the factor truncated at each decimal place:
| Decimals kept | Factor | 137 m² becomes | Error |
|---|---|---|---|
| 0 | 0 | 0 | 100.0000% |
| 1 | 0 | 0 | 100.0000% |
| 2 | 0 | 0 | 100.0000% |
| 3 | 0 | 0 | 100.0000% |
| 4 | 0.0001 | 0.0137 | — |
The right number of significant figures is set by your input, not by the converter. If you measured square meters to three significant figures, the answer in hectares is only good to three — writing more digits claims precision the measurement never had.
