What is Nautical Mile?

The nautical mile is a unit of distance used in maritime and air navigation, defined as exactly 1,852 meters. It was originally based on one minute of arc of latitude along any meridian of the Earth, making it naturally suited for navigation on charts. The knot, a unit of speed equal to one nautical mile per hour, is derived from this unit. Nautical miles are used internationally for charting sea and air routes, and they remain the standard in maritime law and international treaties governing territorial waters.

What is Inch?

The inch is a unit of length in the imperial and US customary systems, defined as exactly 25.4 millimeters. The word comes from the Latin "uncia," meaning one-twelfth, as there are 12 inches in a foot. Screen sizes for televisions, monitors, and smartphones are universally measured diagonally in inches. In plumbing and hardware, pipe diameters and bolt sizes are often specified in inches, even in countries that otherwise use the metric system.
