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 7200 millimeters into kilometers we have to multiply 7200 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

7200 mm → L_(km)

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

L_(km) = 7200 mm × 1.0E-6 km

L_(km) = 0.0072 km

The final result is:

7200 mm → 0.0072 km

We conclude that 7200 millimeters is equivalent to 0.0072 kilometers:

7200 millimeters = 0.0072 kilometers
