Conversion Formula
Gm = pm × 1.000000000e-21
About Picometers
A picometer (pm) is one trillionth of a meter (10⁻¹² m), making it 1,000 times larger than a femtometer but still unimaginably small. This unit is crucial in atomic and molecular physics, as it represents the scale of atomic radii and chemical bonds. For example, a hydrogen atom has a radius of about 53 picometers, and the length of a typical chemical bond ranges from 100 to 200 picometers. X-ray wavelengths also fall within this range.
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.
