Standard Gravity to Gal (g to Gal)
Convert g to Gal — Acceleration converter
One standard gravity equals 980.665 Gal, so to convert g to gals you multiply the value by 980.665. A standard gravity is larger than a gal — going the other way, 1 Gal = 0.0010197162 g. For example, 10 g = 9806.65 Gal and 50 g = 49033.25 Gal.
1 g = 980.665 Gal
Standard Gravity to Gal formula
1 Standard Gravity = 980.665 Gal
Worked examples
- 25 g = 24516.63 Gal
- 100 g = 98066.5 Gal

Standard gravity is a defined constant
Standard gravity is a defined constant, not a measurement: g₀ = 9.80665 m/s² exactly, fixed by the 3rd CGPM in 1901. Every conversion between g and metric or imperial acceleration units on this page uses that exact figure. Local gravity varies by roughly ±0.3% with latitude and altitude, so a precise local value will differ slightly from the standard one.
Expressing acceleration in g is a convention, not a separate physical quantity — it simply reports acceleration as a multiple of g₀. On this page, 1 g = 980.665 Gal.
The gal (Gal, named for Galileo) is a CGS unit used almost exclusively in geophysics and gravimetry: 1 Gal = 1 cm/s² = 0.01 m/s². Survey work usually reports anomalies in milligals, where 1 mGal = 10⁻⁵ m/s².
Context for the numbers: a passenger car braking hard reaches roughly 1 g, a commercial airliner takes off at well under 0.5 g, and sustained exposure above about 5 g requires training and equipment.
