Hectares to Square Meters
Convert hectares (ha) to square meters (m²). Both measure surface measurement, and the conversion comes up in real estate, farming, construction work.
The Formula
``
square meters = hectares × 10000
hectares = square meters × 0.0001
`
One hectare is 10,000 square meters, and one square meter is 1.0000e-4 hectares.
Conversion Table
| 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 |
The Other Direction
| 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 |
What Each Unit Is
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.
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.
A Sense of Scale
A hectare is about 2.47 acres- A rugby pitch is roughly 1 hectare
- A parking space is about 12 m²
- A small flat is 45 m²
- A tennis court is 261 m²
Precision
The factor 10000 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 hectareToSquareMeter = (value) => value * 10000;

How Many Decimals Do You Need?
Rounding the factor costs accuracy, and how much depends on the factor. Converting 137 ha with the factor truncated at each decimal place:
| Decimals kept | Factor | 137 ha becomes | Error |
|---|---|---|---|
| 0 | 10000 | 1,370,000 | — |
| 1 | 10000 | 1,370,000 | — |
| 2 | 10000 | 1,370,000 | — |
| 3 | 10000 | 1,370,000 | — |
| 4 | 10000 | 1,370,000 | — |
The right number of significant figures is set by your input, not by the converter. If you measured hectares to three significant figures, the answer in square meters is only good to three — writing more digits claims precision the measurement never had.
