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.

Centimeter (cm)

Definition: A centimeter (symbol: cm) is a unit of length equal to one hundredth of a meter (0.01 m) in the metric system. It provides a practical scale for everyday measurements.

History: Introduced with the metric system in 1795, the centimeter was designed to bridge the gap between the meter (too large for small objects) and the millimeter (too small for casual use). Its definition inherits all revisions of the meter.

Current use: Widely used globally (except in the US) for measuring body height, clothing sizes, and household objects. Common in medical settings (e.g., tumor sizes) and engineering drawings.
