Feet (ft) to Nanometers (nm) Conversion
Feet
The foot is a unit of length equal to exactly 0.3048 metres, defined by the international yard and pound agreement of 1959. Today it is the primary unit of height measurement in the United States and the United Kingdom, and is used in aviation worldwide to express altitude, where flight levels are defined in hundreds of feet. One foot equals 12 inches and one third of a yard.
Nanometers
The nanometre is a unit of length equal to one billionth of a metre (10⁻⁹ m) and represents the fundamental scale of atomic and molecular structures. The diameter of a hydrogen atom is approximately 0.1 nm, a DNA double helix is about 2 nm wide, and a typical protein ranges from 1 to 100 nm. The nanometre is the primary unit in nanotechnology, materials science, and optics: the wavelength of visible light spans roughly 380–700 nm.
