The SI unit of acceleration is metre per second squared (m/s²), often written m·s⁻².
Acceleration = change in velocity / time, so it has dimensions of length/time² (L·T⁻²). Other common units include:
- centimetre per second squared (cm/s²) in CGS
- feet per second squared (ft/s²) in imperial units
- "g" (standard gravity), where 1 g ≈ 9.80665 m/s².
