Conversion derivation

Express both m² and km² in the same base unit m² (square meter), then cancel the shared base unit.

1
Rewrite m² in the base unit
$1 m^{2} = 1 m^{2}$
2
Rewrite km² in the base unit
$1 k m^{2} = 1, 000, 000 m^{2}$
3
Forward conversion
$1 m^{2} = \frac{1 m ^{2}}{1 , 000 , 000 m ^{2}} \times 1 k m^{2} = \frac{1}{1 , 000 , 000} k m^{2} = 0.000001 k m^{2}$
4
Reverse conversion
$1 k m^{2} = \frac{1 , 000 , 000 m ^{2}}{1 m ^{2}} \times 1 m^{2} = \frac{1 , 000 , 000}{1} m^{2} = 1, 000, 000 m^{2}$

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.
