Meters (m) to Nanometers (nm) Conversion
Meters
The metre is the SI base unit of length, defined since 1983 as the distance light travels in a vacuum in exactly 1/299,792,458 of a second, anchoring its definition to a universal physical constant rather than any material artefact. Introduced by the French Academy of Sciences in 1791 as one ten-millionth of the distance from the equator to the North Pole, the metre became the cornerstone of the metric system and is today the official unit of length in every country that has adopted SI. In science and engineering, virtually all derived units of length, area, volume, and many physical quantities are expressed in terms of the metre.
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.
