About Inch (in)
An imperial unit of length equal to 1/12 of a foot (25.4 millimeters exactly). Inches are the everyday US unit for body height, screen and TV diagonal sizes, paper margins, plumbing fittings (pipe diameters), and tool dimensions. The international inch was fixed at exactly 25.4 mm by the 1959 yard-and-pound agreement. Despite most global industries switching to millimeters, inches are still dominant in US manufacturing, woodworking, and consumer electronics sizing — notably the ubiquitous "55-inch TV" style spec.
About Nautical Mile (nmi)
A unit of length used in maritime and air navigation, equal to exactly 1,852 meters (about 1.151 statute miles). The nautical mile was defined to equal one minute of arc of latitude along any meridian, making it uniquely useful for chart plotting — one degree of latitude is 60 nautical miles anywhere on Earth. International shipping, commercial aviation, and maritime speed (measured in knots, or nautical miles per hour) all use nautical miles as their native unit because the math of navigation is dramatically simpler than with statute miles.
