## 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 25 centimeters into millimeters we have to multiply 25 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

25 cm → L(mm)

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

L(mm) = 25 cm × 10 mm

L(mm) = 250 mm

The final result is:

25 cm → 250 mm

We conclude that 25 centimeters is equivalent to 250 millimeters:

25 centimeters = 250 millimeters

## Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 millimeter is equal to 0.004 × 25 centimeters.

Another way is saying that 25 centimeters is equal to 1 ÷ 0.004 millimeters.

## Approximate result

For practical purposes we can round our final result to an approximate numerical value. We can say that twenty-five centimeters is approximately two hundred fifty millimeters:

25 cm ≅ 250 mm

An alternative is also that one millimeter is approximately zero point zero zero four times twenty-five centimeters.
