Tips & common mistakes

Quick tips

  • 1 nautical mile = 1.852 km = 1.151 statute miles.
  • A knot (1 nmi/h) equals 1.852 km/h — remember this for weather and sailing reports.
  • Latitude is measured in degrees and minutes; one minute of latitude equals exactly one nautical mile.

Avoid these

  • Confusing nautical miles with statute miles — the 15% difference matters in flight planning.
  • Reading knots as km/h on weather reports — a 40-knot wind is 74 km/h, not 40.
  • Using nautical miles on land — outside navigation contexts, use kilometres or statute miles.
