Cubic kilometer to cubic centimeters Conversion
1 cubic kilometer (km³) is equal to 1000000000000000 cubic centimeters (cm³).
1 km³ = 1000000000000000 cm³
or
1 cm³ = 0.000000000000001 km³
Formula
To convert a volume from cubic kilometer (km³) to cubic centimeters (cm³), multiply the volume in cubic kilometer by 1000000000000000
v(cm³) = v(km³) × 1000000000000000
Examples:
Convert 20 cubic kilometer to cubic centimeters:
v(cm³) = 20km³ × 1000000000000000 = 20000000000000000 cm³
