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 an Inch?
An inch is exactly 2.54 centimeters — a rare case where an imperial and a metric unit line up on a tidy number, because the inch was redefined in terms of the meter rather than the other way round. It has quietly outlived most imperial units by attaching itself to technology: screen sizes, wheel and tyre diameters, plumbing pipe, and screw threads are specified in inches worldwide, so even in thoroughly metric countries people buy a 15-inch laptop and 17-inch wheels.
To put both in perspective: a nautical mile is one minute of latitude on any chart, while an inch is about the width of an adult thumb.
