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 120 millimeters into kilometers we have to multiply 120 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

120 mm → L_(km)

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

L_(km) = 120 mm × 1.0E-6 km

L_(km) = 0.00012 km

The final result is:

120 mm → 0.00012 km

We conclude that 120 millimeters is equivalent to 0.00012 kilometers:

120 millimeters = 0.00012 kilometers

Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 kilometer is equal to 8333.3333333333 × 120 millimeters.

Another way is saying that 120 millimeters is equal to 1 ÷ 8333.3333333333 kilometers.

Approximate result

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

120 mm ≅ 0 km

An alternative is also that one kilometer is approximately eight thousand three hundred thirty-three point three three three times one hundred twenty millimeters.
