What is a Nautical Mile?
A nautical mile is exactly 1,852 meters, and unlike every other unit here it was chosen to mean something geographically: it is one minute of latitude, one sixtieth of a degree. That is enormously convenient at sea and in the air, because a navigator can read distance straight off a chart’s latitude scale with dividers and no arithmetic. It is also the parent of the knot — one nautical mile per hour — which is why ships and aircraft report speed in knots rather than km/h.
What is a Mile?
The mile descends from the Roman mille passus — a thousand paces, each pace being two steps. Its modern length of exactly 1,609.344 meters looks arbitrary because it is: the figure was fixed by the 1959 international yard and pound agreement, which defined the yard as exactly 0.9144 meters and let the mile fall out of it at 1,760 yards. It remains the road-distance unit of the United States and the United Kingdom, and the unit runners think in for road races.
To put both in perspective: a nautical mile is one minute of latitude on any chart, while a mile takes most people fifteen to twenty minutes to walk.
