Definition: 12 inches, or exactly 0.3048 meters.
History: The foot traces back to the Roman "pes," and different versions of it were used across Greek, Roman, English, Chinese, and French systems, each a slightly different length depending on who was measuring. English legend credits King Henry I with standardizing it in the 12th century using his own foot as the template - likely a booted foot, since people (and their footwear) tended to run smaller back then. It took until 1959 for the US, UK, and four other countries to finally agree on one exact, shared definition.
Current use: Building and construction measurements, room dimensions, and aircraft altitude are still commonly given in feet, even in countries that otherwise use metric.
Definition: 1/100 of a meter - the "centi" prefix doing the same job it does in "century" or "cent."
History: Introduced alongside the meter itself during the French Revolution's metric overhaul, the centimeter was designed from the start to be a convenient, everyday-sized subdivision - a meter is often too big and a millimeter too small for describing things like a person's height or a book's thickness.
Current use: Height, everyday object sizes, and fabric measurements across most of the world; also the standard unit doctors use internationally for body measurements.
