Delta H is change in enthalpy while delta U is change in internal energy. The units for each is joules.

Enthalpy includes internal energy. Enthalpy is the sum of the internal energy and the product of the pressure and volume of the system.
Internal energy is the sum of the potential energy and the kinetic energy of the system.
The unit for both is joules.
