About feet
The foot is one of the most intuitive ancient units, originally based on the length of a human foot. Almost every culture had its own version, from the Greek 'pous' to the Roman 'pes'. The standardization of the foot was crucial for trade and construction. Today, the International Foot is defined as exactly 0.3048 meters. It remains the dominant unit for aviation altitude worldwide, even in metric-dominant countries. feet are commonly used in Human height (US/UK/Canada), Aviation altitude (worldwide), Real estate square footage, and Lumber length, Boat length.
A standard subway sandwich is nominally 1 foot long.
About nautical miles
The nautical mile is distinct from the statute mile, designed specifically for navigation. It was originally defined as one minute of latitude along any meridian, making it directly compatible with map coordinates. This allowed sailors to measure distance using the stars and a sextant. In 1929, it was standardized to exactly 1,852 meters. It is the basis for the 'knot' (one nautical mile per hour). nautical miles are commonly used in Ship navigation, Aircraft flight planning, International law (territorial waters), and Polar exploration, Meteorological forecasts.
A nautical mile is about 15% longer than a standard land mile.
