## 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 29.1 centimeters into millimeters we have to multiply 29.1 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

29.1 cm → L(mm)

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

L(mm) = 29.1 cm × 10 mm

L(mm) = 291 mm

The final result is:

29.1 cm → 291 mm

We conclude that 29.1 centimeters is equivalent to 291 millimeters:

29.1 centimeters = 291 millimeters
