What units should I use?

Use consistent units (e.g. m, m/s, m/s², s). The result will be in the same length unit as velocity × time.

Does this work for deceleration?

Yes. Use negative acceleration for deceleration.

Initial velocity at time t = 0.

Calculate displacement using s = v₀t + ½at² (initial velocity, acceleration, time).
