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 500 millimeters into kilometers we have to multiply 500 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

500 mm → L_(km)

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

L_(km) = 500 mm × 1.0E-6 km

L_(km) = 0.0005 km

The final result is:

500 mm → 0.0005 km

We conclude that 500 millimeters is equivalent to 0.0005 kilometers:

500 millimeters = 0.0005 kilometers

Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 kilometer is equal to 2000 × 500 millimeters.

Another way is saying that 500 millimeters is equal to 1 ÷ 2000 kilometers.

Approximate result

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

500 mm ≅ 0.001 km

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