Inches (in)

Definition

An inch (in) is an imperial unit of length equal to 1/12 of a foot or exactly 25.4 millimeters.

History

The inch has ancient origins, historically defined as the width of a man's thumb. It was standardized internationally in 1959 to exactly 25.4 mm. The word 'inch' derives from the Latin 'uncia' meaning one-twelfth.

Current use

Inches are widely used in the United States, Canada, and the United Kingdom for everyday measurements: screen sizes, paper dimensions, height measurements, pipe diameters, and construction specifications.

Nanometers (nm)

Definition

A nanometer (nm) is a metric unit of length equal to one billionth of a meter (10⁻⁹ m). It is part of the International System of Units (SI).

History

The nanometer became important in the 20th century with advances in microscopy and semiconductor technology. The prefix 'nano' comes from the Greek word 'nanos' meaning dwarf.

Current use

Nanometers are essential in nanotechnology, semiconductor manufacturing (chip node sizes like 5 nm, 3 nm), molecular biology (DNA strand width ~2.5 nm), and light wavelength measurement (visible light: 380–700 nm).
