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 800 centimeters into millimeters we have to multiply 800 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

800 cm → L_(mm)

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

L_(mm) = 800 cm × 10 mm

L_(mm) = 8000 mm

The final result is:

800 cm → 8000 mm

We conclude that 800 centimeters is equivalent to 8000 millimeters:

800 centimeters = 8000 millimeters

Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 millimeter is equal to 0.000125 × 800 centimeters.

Another way is saying that 800 centimeters is equal to 1 ÷ 0.000125 millimeters.

Approximate result

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

800 cm ≅ 8000 mm

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