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 1500 millimeters into kilometers we have to multiply 1500 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

1500 mm → L_(km)

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

L_(km) = 1500 mm × 1.0E-6 km

L_(km) = 0.0015 km

The final result is:

1500 mm → 0.0015 km

We conclude that 1500 millimeters is equivalent to 0.0015 kilometers:

1500 millimeters = 0.0015 kilometers

Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 kilometer is equal to 666.66666666667 × 1500 millimeters.

Another way is saying that 1500 millimeters is equal to 1 ÷ 666.66666666667 kilometers.

Approximate result

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

1500 mm ≅ 0.002 km

An alternative is also that one kilometer is approximately six hundred sixty-six point six six seven times one thousand five hundred millimeters.
