Last updated by rainer at 2015/4/20

The length unit includes meter (m), centimeter (cm), millimeter (mm), kilometer (km), micrometer (μm), nanometer (nm) and nautical mile (n mile). The relations among them are as follows:

1 m = 100 cm = 1000 mm = 10-3 km = 106μm = 109 nm

1 n mile = 1852 m = 1.852 km
