I think I kind of get the gist of enthalpy and entropy, but i have no idea what temperature is.
Temperature is a measure of kinetic energy on the particle scale.
Quantum mechanically, temperature is expressed in the rotational and vibrational states of atoms and molecules.

They're trying to pin down all the physical constants to a minimum number of constants deemed the "most fundamental" which is ultimately a silly task, IMO, but standardizing units and definitions is important.
