About Millimeter (mm)
A metric unit of length equal to one thousandth of a meter (0.001 m), about the thickness of a credit card. Millimeters are the default unit in mechanical engineering drawings, manufacturing tolerances, rainfall measurement, and precision machining. Camera focal lengths, bullet calibers (outside the US), and tire dimensions are routinely quoted in millimeters because the unit sits right at the edge of what the human eye can distinguish unaided.
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.
