AI explanation for this conversion
This pre-generated explanation is schema-checked. Numeric results still come from the page formula and calculator.
Why 1 km² equals 100 ha
The conversion factor holds because both the square kilometer and the hectare are defined in terms of the square meter. One square kilometer equals 1,000,000 square meters, and one hectare equals 10,000 square meters. Dividing these values gives the factor of 100.
Definition
A square kilometer (km²) is a unit of area in the metric system, equal to the area of a square with sides of one kilometer. A hectare (ha) is also a metric unit of area, defined as the area of a square with sides of one hundred meters.
Principle
The conversion uses the common base unit of the square meter (m²). By expressing both area units in m², the relationship between them is derived from the ratio of their base unit equivalents. The factor is obtained by dividing 1,000,000 by 10,000.
Assumptions
- The conversion is based on the metric definitions: 1 km² = 1,000,000 m² and 1 ha = 10,000 m².
- The factor is exact and does not account for rounding in calculations.
Cautions
- When performing calculations, round the result to the precision required by your specific application.
- The conversion factor applies only to area measurements, not to lengths or other dimensions.
