# In which conditions can the self-consistent Hubbard U value calculated using Quantum Espresso be used for other VASP calculations?

I have seen that some articles calculate Hubbard $$U$$ value self-consistently using Quantum Espresso code. Then, they use it in VASP calculations. My question is: In which conditions can this value be transferred from a code to another?
