Gal to Inch per Second Squared (Gal to in/s²)
Convert Gal to in/s² — Acceleration converter
Also written as Gal to in/s2.
One gal equals 0.39370079 in/s², so to convert gals to inches per second squared you multiply the value by 0.39370079. A gal is smaller than a inch per second squared — going the other way, 1 in/s² = 2.54 Gal. For example, 10 Gal = 3.937008 in/s² and 50 Gal = 19.685039 in/s².
1 Gal = 0.39370079 in/s²
Gal to Inch per Second Squared formula
1 Gal = 0.39370079 in/s²
Worked examples
- 25 Gal = 9.84252 in/s²
- 100 Gal = 39.370079 in/s²

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 Gal = 0.39370079 in/s².
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.
