## 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 300 centimeters into millimeters we have to multiply 300 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

300 cm → L(mm)

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

L(mm) = 300 cm × 10 mm

L(mm) = 3000 mm

The final result is:

300 cm → 3000 mm

We conclude that 300 centimeters is equivalent to 3000 millimeters:

300 centimeters = 3000 millimeters

## Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 millimeter is equal to 0.00033333333333333 × 300 centimeters.

Another way is saying that 300 centimeters is equal to 1 ÷ 0.00033333333333333 millimeters.

## Approximate result

For practical purposes we can round our final result to an approximate numerical value. We can say that three hundred centimeters is approximately three thousand millimeters:

300 cm ≅ 3000 mm

An alternative is also that one millimeter is approximately zero times three hundred centimeters.
