m2 to km2 Converter - Square Meter to Square Kilometer
Square Meter (m²) (m2) to Square Kilometer (km²) (km2)
Direct answer
1 m2 = 0.000001 km2
km2 = m2 × 0.000001
Converter
Conversion formula
km2 = m2 × 0.000001
m2 = km2 × 1,000,000
Example: 10 m2 = 10 × 0.000001 = 0.00001 km2.

Conversion from Square Meter (m²) to Square Kilometer (km²)
The conversion factor from m² to km² is 0.000001. This factor arises because both are metric units of area derived from the same length base unit.
Definition
Square meter (m²) is the SI unit of area. Square kilometer (km²) is a metric unit of area equal to 1,000,000 m².
Principle
The conversion is based on expressing both units in terms of the shared base unit of square meters (m²). One square kilometer equals 1,000,000 square meters.
Assumptions
- Both units are in the metric system and share the meter as a base length unit.
- The conversion factor is exact within the metric system.
Cautions
- The conversion applies only to area measurements, not to other physical quantities.
- Ensure consistent use of the units; 1 km² is exactly 1,000,000 m².
