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 250 centimeters into millimeters we have to multiply 250 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

250 cm → L_(mm)

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

L_(mm) = 250 cm × 10 mm

L_(mm) = 2500 mm

The final result is:

250 cm → 2500 mm

We conclude that 250 centimeters is equivalent to 2500 millimeters:

250 centimeters = 2500 millimeters
