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 1200 centimeters into millimeters we have to multiply 1200 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

1200 cm → L_(mm)

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

L_(mm) = 1200 cm × 10 mm

L_(mm) = 12000 mm

The final result is:

1200 cm → 12000 mm

We conclude that 1200 centimeters is equivalent to 12000 millimeters:

1200 centimeters = 12000 millimeters
