If you want to calculate the percent for each ingredient simple divide the weight of each ingredient by the weight of the flour and multiply by 100. Remember, flour is always 100%. For example, 50-pounds of flour and 4-ounces of yeast. What is the percent of yeast? First, the ingredient and flour weight must be in the same weight units (pounds, ounces, grams, kilograms, etc.) Lets do it in ounces; 50 X 16 = 800 So, 4 divided by 800 = 0.005 X100 = 0.5%
If you want to calculate the weight of each ingredient for 50-pounds of flour, and you already have the ingredient percentages ( say 1.75%) this is what you do: Using a calculator, enter the flour weight, in this case 50 X 1.75 then press the “%” key and read the answer ( 0.875-pounds) in the display window. Remember, the answer will always be in the same weight units as the flour is shown in. To change the above answer to ounces, simply multiply by 16; 0.875 X 16 =14-ounces.
I hope this helps.
