Short background on the units used in this conversion.
The foot per square second (ft/s²) is an imperial acceleration unit equal to 0.3048 m/s².
Feet per square second appear in US automotive, aerospace, and ballistics references when speeds are given in feet per second.
The meter per square second (m/s²) is the SI unit of acceleration — how quickly velocity changes, in meters per second every second.
Meters per square second appear in physics problems, vehicle crash testing, and ISO engineering specifications worldwide.
m/s² = ft/s² × 0.3048ft/s² = m/s² × 3.280839895, using the same exact factors as this converter.Jump to any acceleration conversion starting from foot per square second — including the reverse direction and every other unit in our dataset.
