Converting potentials between different reference

Jul 04, 2015 · Similarly, finding the measured potential vs calomel is the same as finding the blue vector. We can do this by adding the difference of the 2 grey vectors to the red vector. Some sites may give the potential of the reference electrode relative to NHE, RHE, SCE etc. instead of SHE.
