The inch is defined as exactly 2.54 centimeters (international agreement of 1959). It is used in the US and UK for screen sizes, lumber, fasteners and body height.
The nautical mile is exactly 1,852 meters, originally one minute of latitude. It is used in aviation and at sea, together with the knot.
Use the formula nmi = in × 0.00001371490281. For example, 10 in = 0.0001371490281 nmi.
1 in = 0.00001371490281 nmi.
Use in = nmi × 72,913.38583. 1 nmi = 72,913.38583 in.
