About these units

Meter per Second Squared (m/s²)

Definition
Meters per second squared (m/s²) is the SI unit of acceleration, the rate of change of velocity each second.
History
It follows directly from the SI units of length and time.
Current use
It is the standard acceleration unit in physics and engineering.

Standard Gravity (g)

Definition
Standard gravity (g) is the nominal acceleration of free fall at Earth’s surface, defined as 9.80665 m/s².
History
It was standardised so weights and forces could be defined consistently.
Current use
It expresses g-forces in aviation, vehicle dynamics, and spaceflight.

Foot per Second Squared (ft/s²)

Definition
Feet per second squared (ft/s²) is the imperial unit of acceleration.
History
It comes from the imperial system of mechanics.
Current use
It expresses acceleration in US physics and engineering problems.

Inch per Second Squared (in/s²)

Definition
Inches per second squared (in/s²) is a small imperial acceleration unit for fine motion.
History
It is the small-scale counterpart of feet per second squared.
Current use
It describes acceleration in precision mechanisms and motion control.

Galileo (Gal)

Definition
A galileo (Gal) is a CGS acceleration unit equal to one centimeter per second squared.
History
Named after Galileo Galilei, it is used in geodesy and gravimetry.
Current use
Galileos (and milligals) measure tiny variations in Earth’s gravity.

Kilometer per Hour per Second (km/h/s)

Definition
Kilometers per hour per second (km/h/s) expresses how quickly speed in km/h changes each second.
History
It arose as an intuitive way to describe vehicle acceleration.
Current use
It is used informally to describe how fast a vehicle gains speed.
