The $\textit{Galileo}$ is the unit of acceleration of free fall used extensively in the science of gravimetry. The Galileo is defined as $1 \textit{centimeter per square second}$ ($1 cm/s^2$). Unfortunately, the Galileo is often denoted with the symbol Gal, not to be confused with the Gallon that also uses the same symbol.
CGS unit of acceleration called gal with the definition: 1 Gal = 1 cm/s
