1 cm = 10 mm

To convert 1.3 centimeters into millimeters we have to multiply 1.3 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

1.3 cm → L(mm)

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

L(mm) = 1.3 cm × 10 mm

L(mm) = 13 mm

The final result is:

1.3 cm → 13 mm

We conclude that 1.3 centimeters is equivalent to 13 millimeters:

1.3 centimeters = 13 millimeters
