Nautical Miles to Kilometersnmi → km
1 nmi = 1.852 km · 1 km = 0.539957 nmi
Formula
km = nmi × 1.852
Example: 15 nmi = 15 × 1.852 = 27.78 km
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.
