A hectare is a metric land-area unit equal to 10,000 square meters.
Hectares are widely used in agriculture, forestry, conservation, and land administration because they fit parcel-scale land work.
ha is used for farms, forests, parks, land parcels, reserves, planning zones, and managed landscapes.
A square kilometer is a metric area unit equal to one million square meters.
Square kilometers are common in geography, public statistics, mapping, and regional land reporting.
km2 is used for cities, districts, parks, watersheds, reserves, and other large mapped surfaces.
Mathematically, square kilometer (km²) = hectare (ha) converted with the formula below.
1 ha = 0.01 km²
1 km² = 100 ha
Formula: value × 0.01
Example: 15 ha = 0.15 km²
Precision note: The ha to km2 conversion is exact. Display enough decimal places for smaller land areas so meaningful parcels are not rounded away.
1 ha = 0.01 km²
1 km² = 100 ha
| Hectare [ha] | Square kilometer [km²] |
|---|---|
| 0.01 ha | 0.0001 km² |
| 0.1 ha | 0.001 km² |
| 1 ha | 0.01 km² |
| 2 ha | 0.02 km² |
| 5 ha | 0.05 km² |
| 10 ha | 0.1 km² |
| 20 ha | 0.2 km² |
| 50 ha | 0.5 km² |
| 100 ha | 1 km² |
One hectare is exactly 0.01 square kilometers. One square kilometer equals 100 hectares.
A square kilometer is larger than a hectare, so the same land area uses fewer square kilometers.
Use km2 when comparing large regions, mapped areas, parks, districts, or public geography data. Use hectares for parcel, farm, forestry, or land-management detail.
