λ and Δλ have the same units. So the unit of V should be the same as C. So, if for C you use 300.000m/s you will use m/s as your unit. There are other possible units you may use, like km/s, km/h ect. But after you solve the equation (V= (Δλ / λ) C ) the unit you will use should be the same as the unit you used for C.
