Inch per Second Squared to Foot per Second Squared (in/s² to ft/s²)
Convert in/s² to ft/s² — Acceleration converter
Also written as in/s2 to ft/s2.
One inch per second squared equals 0.08333333 ft/s², so to convert inches per second squared to feet per second squared you multiply the value by 0.08333333. A inch per second squared is smaller than a foot per second squared — going the other way, 1 ft/s² = 12 in/s². For example, 10 in/s² = 0.83333333 ft/s² and 50 in/s² = 4.166667 ft/s².
1 in/s² = 0.08333333 ft/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 in/s² = 0.08333333 ft/s².
