Angstrom is a length unit used to express distance, size or travel range in practical measurement work.
Named after Swedish physicist Anders Jonas Ångström, who used 10⁻¹⁰ meters to tabulate the wavelengths of sunlight in the 1860s. It is not an SI unit but remains common in crystallography and spectroscopy.
Measurement system: Metric, imperial and internationally standardized length usage. SI equivalent: 1 Å = 1.000000e-10 m.
