1st value(Say 'V1') : 0.316815906659 ( Unit = ? )
2nd value(Say 'V2') : 0.344911681094 ( Unit = ? )
1st value - 2nd value = V1-V2 = 0.028095774435 ( Unit = ? )

actual time in milliseconds that has passed between measuring(say 't'): 1sec = 1000 milliseconds

therefore final answer = (V1-V2)/t = 0.000028095774435  ( Unit = ? )

Please correct me wherever I am going wrong in computation...
