To convert 29.7 centimeters into millimeters we have to multiply 29.7 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

29.7 cm → L(mm)

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

L(mm) = 29.7 cm × 10 mm

L(mm) = 297 mm

The final result is:

29.7 cm → 297 mm

We conclude that 29.7 centimeters is equivalent to 297 millimeters:

29.7 centimeters = 297 millimeters
