Kilometers to Nautical Mileskm → nmi
1 km = 0.539957 nmi · 1 nmi = 1.852 km
Formula
nmi = km ÷ 1.852
Example: 42.195 km = 42.195 ÷ 1.852 = 22.7835 nmi
These units differ only by a fixed factor: multiply by it to convert, divide to go back. The factors are exact international definitions (for example 1 inch = 2.54 cm exactly); results are rounded only for display.
