Standard Gravity to Inch per Second Squared (g to in/s²)
Convert g to in/s² — Acceleration converter
Also written as g to in/s2.
One standard gravity equals 386.088583 in/s², so to convert g to inches per second squared you multiply the value by 386.088583. A standard gravity is larger than a inch per second squared — going the other way, 1 in/s² = 0.0025900792 g. For example, 10 g = 3860.89 in/s² and 50 g = 19304.43 in/s².
1 g = 386.088583 in/s²
Standard Gravity to Inch per Second Squared formula
1 Standard Gravity = 386.088583 in/s²
Worked examples
- 25 g = 9652.21 in/s²
- 100 g = 38608.86 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 g = 386.088583 in/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.
