To convert 34.5 centimeters into millimeters we have to multiply 34.5 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

34.5 cm → L(mm)

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

L(mm) = 34.5 cm × 10 mm

L(mm) = 345 mm

The final result is:

34.5 cm → 345 mm

We conclude that 34.5 centimeters is equivalent to 345 millimeters:

34.5 centimeters = 345 millimeters
