Gal (unit)
From Biocrawler, the free encyclopedia.
(Redirected from Galileo (unit))
The gal or galileo is the CGS unit of acceleration. It is defined as 1 centimetre per second squared. The symbol for the gal is Gal.
In SI units: 1 Gal = 0.01 m/s².
The acceleration due to gravity at the Earth's surface is approximately 981 Gal. Variations in gravitational acceleration, such as may be due to mountains or masses of lesser density within the Earth's crust, are typically tens to hundreds of milligals (mGal).
The gal is named after Galileo Galilei, a physicist who made the first measurements of the acceleration due to gravity.fr:gal
