About the Nautical Mile Converter

Under the hood, this converter applies km = nmi × 1.852; statute miles = nmi × 1.15078; ft = nmi × 6,076.12, so the nautical mile converter result you see is genuine math, not a lookup table.

For context, the sections beneath the converter include typical values, a worked example you can recompute by hand, and an FAQ covering the practical details of nautical mile converter.

functions Shows the working, not just the answer

For students and teachers, the final number is only half the value. Every math tool here exposes the formula it applied, the intermediate steps, and the rounding rule, so you can follow along, check your homework, or use the answer in a proof or report with confidence.

calculate Accurate to the spec

Calculations use 64-bit floating point with sensible rounding for the domain (currency to 2 decimals, percentages to 4 decimals, algebra to 6 significant figures). Where exact rational arithmetic matters — fractions, factorials, simplification — we use a dedicated BigNumber path so 1/3 + 1/6 returns ½, not 0.49999.

Formula & methodology

Formula: km = nmi × 1.852; statute miles = nmi × 1.15078; ft = nmi × 6,076.12

  1. Enter the distance in nautical miles.
  2. Multiply by 1.852 for kilometers (exact).
  3. Multiply by 1.15078 for statute (land) miles.
  4. Multiply by 6,076.12 for feet.

Example: 10 nmi = 18.52 km = 11.5078 mi = 60,761 ft.

Frequently asked questions

How long is a nautical mile?
Exactly 1,852 meters — about 1.15 land miles or 6,076 feet. It was defined as one minute of latitude along a meridian.
How do I convert nautical miles to km?
Multiply by 1.852. 10 nmi = 18.52 km, exactly — the definition is metric.
Why do ships and planes use nautical miles?
Because 1 nmi = 1 arcminute of latitude, distances read directly off charts: 1 degree = 60 nmi, no conversion needed.
What is a knot?
One nautical mile per hour — 20 knots is 23 mph or 37 km/h.
Is a nautical mile longer than a regular mile?
Yes, about 15% longer: 6,076 ft vs 5,280 ft.
