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 1200 millimeters into kilometers we have to multiply 1200 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

1200 mm → L_(km)

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

L_(km) = 1200 mm × 1.0E-6 km

L_(km) = 0.0012 km

The final result is:

1200 mm → 0.0012 km

We conclude that 1200 millimeters is equivalent to 0.0012 kilometers:

1200 millimeters = 0.0012 kilometers

Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 kilometer is equal to 833.33333333333 × 1200 millimeters.

Another way is saying that 1200 millimeters is equal to 1 ÷ 833.33333333333 kilometers.

Approximate result

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

1200 mm ≅ 0.001 km

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