Conversion formula

The conversion factor from centimeters to millimeters is 10, which means that 1 centimeter is equal to 10 millimeters:

1 cm = 10 mm

To convert 300.5 centimeters into millimeters we have to multiply 300.5 by the conversion factor in order to get the length amount from centimeters to millimeters. We can also form a simple proportion to calculate the result:

1 cm → 10 mm

300.5 cm → L_(mm)

Solve the above proportion to obtain the length L in millimeters:

L_(mm) = 300.5 cm × 10 mm

L_(mm) = 3005 mm

The final result is:

300.5 cm → 3005 mm

We conclude that 300.5 centimeters is equivalent to 3005 millimeters:

300.5 centimeters = 3005 millimeters
