Silver, Platinum, Palladium, and Rhodium help

[musicjcmerrr]

Hello all, I am new to this forums and I'm still learning about precious metals. I know how to calculate gold, but I have no clue on how to calculate the price for the other precious metals. If someone would like to add a formula for each, or at least for silver, I would be happy. I know I'm asking for a lot, but I would like to see it in grams. Thank you.
