How to Convert Nautical Mile to Mile
- 1 nmi = 1.150779448 mi
- 1 mi = 0.8689762419 nmi
- Example: convert 15 nmi to mi: 15 nmi = 15 × 1.150779448 mi = 17.26169172 mi
Reference conditions. mi: The international yard and pound agreement (1959) fixed 1 yard = 0.9144 m exactly, so the inch, foot and mile are exact.
Formula
mi = nmi × 1.150779448024
Derivation from SI units:
- 1 nmi = 1852 m (exact, by international agreement, 1929)
- 1 mi = 5280 ft = 5280 × 0.3048 m = 1609.344 m
- 1 nmi = 1852 m ÷ 1609.344 m per mi = 1.150779448024 mi
Both units are defined exactly, so the factor is exact. Nautical Mile definition: nautical mile; Mile definition: mile.
Worked examples
- A reading of 5 nmi converts to 5.75389724 mi.
5 nmi × 1.150779448 = 5.75389724 mi - A value of 100 nmi is 115.0779448 mi.
100 nmi × 1.150779448 = 115.0779448 mi
