Inch (in)

Definition: An inch (symbol: in) is 1/12 of a foot or exactly 25.4 millimeters. It is deeply embedded in US manufacturing and daily life.

History: Derived from the Latin 'uncia' (1/12 of a Roman foot). Standardized internationally in 1959 to 25.4 mm, resolving variations between US and UK inches.

Current use: Prevails in US screen sizes (TVs, monitors), plumbing (pipe diameters), and tool calibration (e.g., wrench sizes). The UK uses inches informally for screen sizes and height.

Meter (m)

Definition: A meter, or metre (symbol: m), is the base unit of length and distance in the International System of Units (SI). The meter is defined as the distance traveled by light in 1/299,792,458 of a second. This definition was slightly modified in 2019 to reflect changes in the definition of the second.

History: Originally, in 1793, the meter was defined as one ten-millionth of the distance from the equator to the North Pole. This changed in 1889, when the International Prototype Metre was established as the length of a prototype meter bar (made of an alloy of 90% platinum and 10% iridium) measured at the melting point of ice. In 1960, the meter was redefined in terms of wavelengths of krypton-86. The current definition (based on the speed of light) was adopted in 1983.

Current use: As the SI unit of length, the meter is used worldwide in science, engineering, and daily life for measuring distance, height, and dimensions. The United States is a notable exception, still primarily using US customary units (feet, miles) for non-scientific applications.
