Acceleration is the change (increase or decrease) in
velocity. It is a vector quantity with dimension length/time². In metric
system, unit of acceleration is meters per second squared.
Velocity is measured with length/time (meters/second etc), so the acceleration
can be calculated as Acceleration = (Final Velocity - Initial Velocity) / Total
Time i.e meters/second/second = meters/second²
This conversion tool converts the most common metric and imperial acceleration
units.
