Length Converter and Distance Converter Definitions


An Angstrom is a non-SI unit of length that is internationally recognized, equal to 0.1 nanometre (nm). It is sometimes used in expressing the sizes of atoms, lengths of chemical bonds and visible-light spectra, and dimensions of parts of integrated circuits. It is commonly applied in structural biology. Full description is available on Wikipedia.

Astronomical Unit
