Yes, the DeBroglie equation uses all SI units. Another way to look at the units involved, is to understand what units are appropriate for each variable involved (this can be found in the textbook or modules). For example, the units for Planck's constant are kg.m^2.s^-1 while the units for velocity is m.s^-1. It is helpful to remember that problems involving the DeBroglie Equation involve cancelling out units to get the proper units of the final answer, so memorizing what the proper units for each variable are, especially Planck's constant, can help you visualize when you need to convert units, and what final units you should end up with.
