What is a nautical mile?
Exactly 1,852 meters by international agreement since 1929, chosen because it is one minute of latitude — which is why a chart, a speed in knots and a position in degrees all use the same arithmetic.
What is an inch?
Exactly 25.4 millimeters since the 1959 international yard and pound agreement, and one twelfth of a foot.
How many inches are in a nautical mile?
One nautical mile is 72913.386 inches. Going the other way, one inch is 1.3715 × 10^-5 nautical miles. Both figures come from the same defined relation rather than from a measurement, which is why they are the same today as they were in 1959.
