Feet (ft)
Definition
A foot (ft) is an imperial unit of length equal to 12 inches or exactly 0.3048 meters.
History
The foot has been used since antiquity — ancient civilizations based it on the length of a human foot. The modern international foot was standardized in 1959 to exactly 0.3048 meters by agreement between English-speaking nations.
Current use
Feet are the standard unit for measuring human height, room dimensions, building elevation, and altitude in aviation in the United States, United Kingdom, Canada, and several other countries.
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).
