To convert 27 millimeters into kilometers we have to multiply 27 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

27 mm → L_(km)

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

L_(km) = 27 mm × 1.0E-6 km

L_(km) = 2.7E-5 km

The final result is:

27 mm → 2.7E-5 km

We conclude that 27 millimeters is equivalent to 2.7E-5 kilometers:

27 millimeters = 2.7E-5 kilometers
