Please provide values below to convert Square Kilometer [km²] to Square Millimeter [mm²], or vice versa.
1 Square Kilometer (km²) = 1,000,000,000,000 Square Millimeter (mm²)
1 Square Millimeter (mm²) = 0.000000000001 Square Kilometer (km²)
Example: convert 15 Square Kilometer (km²) to Square Millimeter (mm²):
15 Square Kilometer (km²) = 15 × 1,000,000,000,000 Square Millimeter (mm²) = 15,000,000,000,000 Square Millimeter (mm²)
A square kilometer equals 1,000,000 square meters. Used for measuring large land areas.
