Foot per Second Squared to Inch per Second Squared (ft/s² to in/s²)
Convert ft/s² to in/s² — Acceleration converter
Also written as ft/s2 to in/s2.
One foot per second squared equals 12 in/s², so to convert feet per second squared to inches per second squared you multiply the value by 12. A foot per second squared is larger than a inch per second squared — going the other way, 1 in/s² = 0.08333333 ft/s². For example, 10 ft/s² = 120 in/s² and 50 ft/s² = 600 in/s².
1 ft/s² = 12 in/s²
Foot per Second Squared to Inch per Second Squared formula
1 Foot per Second Squared = 12 in/s²
Worked examples
- 25 ft/s² = 300 in/s²
- 100 ft/s² = 1200 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 ft/s² = 12 in/s².
