Converting RGB values to percentages (lemmy.world)

I ran across a table of settings for Photoshop's channel mixer for simulating various analog film stocks. However, the RGB color values are given as numbers in the 0-255 range, and channel mixer uses percentages. Any idea how to convert the RGB values to plug them into channel mixer?
