Conversion formula

The conversion factor from millimeters to kilometers is 1.0E-6, which means that 1 millimeter is equal to 1.0E-6 kilometers:

1 mm = 1.0E-6 km

To convert 800 millimeters into kilometers we have to multiply 800 by the conversion factor in order to get the length amount from millimeters to kilometers. We can also form a simple proportion to calculate the result:

1 mm → 1.0E-6 km

800 mm → L_(km)

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

L_(km) = 800 mm × 1.0E-6 km

L_(km) = 0.0008 km

The final result is:

800 mm → 0.0008 km

We conclude that 800 millimeters is equivalent to 0.0008 kilometers:

800 millimeters = 0.0008 kilometers

Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 kilometer is equal to 1250 × 800 millimeters.

Another way is saying that 800 millimeters is equal to 1 ÷ 1250 kilometers.

Approximate result

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

800 mm ≅ 0.001 km

An alternative is also that one kilometer is approximately one thousand two hundred fifty times eight hundred millimeters.
