Conversion formula

The conversion factor from cubic centimeters to milliliters is 1, which means that 1 cubic centimeter is equal to 1 milliliters:

1 cm3 = 1 ml

To convert 645 cubic centimeters into milliliters we have to multiply 645 by the conversion factor in order to get the volume amount from cubic centimeters to milliliters. We can also form a simple proportion to calculate the result:

1 cm3 → 1 ml

645 cm3 → V_(ml)

Solve the above proportion to obtain the volume V in milliliters:

V_(ml) = 645 cm3 × 1 ml

V_(ml) = 645 ml

The final result is:

645 cm3 → 645 ml

We conclude that 645 cubic centimeters is equivalent to 645 milliliters:

645 cubic centimeters = 645 milliliters
