Nautical Miles to Miles
A nautical mile is 1,852 meters, defined as one minute of latitude and used in marine and air navigation. A mile is 1,609.344 meters, the statute mile used on US and UK road signs and speed limits. 1 nmi equals ≈1.15078 mi, so converting between them is a matter of multiplying by that fixed factor — type any value into the converter below and both sides update instantly as you type.
Both units belong to length, measured here against length's base unit (m) — every other length unit on this site converts through that same reference point, which is why the table below can also be read as a quick cross-check against nearby values.
Formula
mi = nmi × ≈1.15078
nmi = mi × ≈0.868976
Worked example: 5 nmi × ≈1.15078 = ≈5.7539 mi.
