km2 to m2 Converter - Square Kilometer to Square Meter
Square Kilometer (km²) (km2) to Square Meter (m²) (m2)
Direct answer
1 km2 = 1,000,000 m2
m2 = km2 × 1,000,000
Converter
Conversion formula
m2 = km2 × 1,000,000
km2 = m2 × 0.000001
Example: 10 km2 = 10 × 1,000,000 = 10,000,000 m2.

Conversion factor from square kilometers to square meters
The conversion factor between square kilometers (km²) and square meters (m²) is based on the relationship between the metric units of length used to define area.
Definition
A square kilometer (km²) is a unit of area, as is a square meter (m²). The conversion factor shows how many square meters are contained in one square kilometer.
Principle
The conversion factor holds because both square kilometers and square meters are derived from the same base unit of length. The factor 1,000,000 represents the ratio of their areas.
Assumptions
- Both units are defined in the metric system.
- The conversion is purely based on the defined relationship between the units.
Cautions
- Always use the exact conversion factor of 1,000,000 for precise calculations.
- Round the result to the precision required by your specific calculation.
