Convert Angstroms to Gigameters
Convert Angstroms (Å) to Gigameters (Gm) instantly and accurately.
Conversion Formula
Gm = Å × 1.000000000e-19
About Angstroms
An angstrom (Å) is equal to 0.1 nanometers or 10⁻¹⁰ meters, named after Swedish physicist Anders Jonas Ångström. While not an official SI unit, it remains widely used in chemistry, solid-state physics, and crystallography to express atomic distances and wavelengths. A typical atom has a diameter of 1-3 angstroms, and the spacing between atoms in crystals is commonly measured in angstroms. X-ray crystallographers use angstroms to describe molecular structures with atomic precision.
About Gigameters
A gigameter (Gm) is one billion meters (10⁹ m), making it useful for planetary measurements and inner solar system distances. The Sun's diameter is about 1.39 Gm, while Jupiter's diameter is roughly 0.14 Gm. The distance from Earth to the Moon is approximately 0.38 Gm. This unit bridges the gap between terrestrial measurements (megameters) and astronomical distances, providing a convenient scale for describing planetary sizes and nearby celestial distances in our solar system.
