The SI units of acceleration are metres per second per second: # ms^-2#.

Explanation:

Acceleration is the rate of change of velocity with time.

Velocity is the rate of change of distance with time.

Time is measured in seconds (#s#), distance in metres (#m#).

The units of velocity are metres per second: m/s = #m/s = ms^-1#.

The units of acceleration are metres per second per second: m/s/s = #(ms^-1)/s = ms^-2#.
