Conversion derivation

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

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

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.
