Gal
The Gal, designated by the symbol Gal, is a CGS unit of acceleration named in honor of the physicist Galileo Galilei. Defined as one centimetre per second squared, one Gal equals exactly 0.01 metres per second squared in SI base units. Although non-SI, the Gal remains widely utilized in geophysics and gravimetry to measure localized variations in Earth's gravitational field, which are critical for geological surveys and sub-surface exploration.
