Acceleration measures how quickly velocity changes over time.
The meter per second squared is the SI derived unit, while standard gravity (g) is a common reference for g-force in vehicles and aerospace.

What is acceleration?
Acceleration is the rate of change of velocity with respect to time.
It is used to describe vehicle performance, free fall, g-forces and mechanical motion.
Standard gravity as a reference
Standard gravity (g = 9.80665 m/s²) is widely used as a reference unit for expressing acceleration relative to Earth's gravitational pull, especially in aerospace and vehicle testing.
Acceleration units in practice
Meters per second squared is the SI unit for acceleration. Feet per second squared appears in customary engineering work, while standard gravity expresses acceleration relative to a defined reference value.
Use g only when the context clearly means standard gravity rather than local gravitational acceleration.
