"Electrochemical Equivalents Chart"

We know from Faraday's Law that the thickness of plating will be proportional to the plating current x the plating time. But running the calculation can be time-consuming and repetitive, depending as it does on the particular atomic weight of the metal being deposited, its valence state, and its density.

To save time and potential errors, every issue of the Metal Finishing Guidebook has an appendix labeled "Electrochemical Equivalents" which does the math for us and tells us how many grams/ounces are deposited per Ampere-Hour, or how many Ampere-Hours are required to deposit 0.001" for each of the commonly plated metals.
