Centimeter per Square Second (cm/s²)
The centimeter per square second (cm/s²) equals 0.01 m/s² — a compact metric scale for moderate accelerations.
Centimeters per square second suit lab instrument readouts and geophysical surveys using the centimeter-gram-second tradition.
Meter per Square Second (m/s²)
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.
