Rule # 1 Get over your math phobia! Calculators are our Friend!
Rule # 2 Know Standard Measurements – Volume (cups, quarts, gallons, and oz. – Weight (16 oz. = 1 lb.)
The Problem Convert 252 oz. of water into something you can measure.

Recipe Conversion
Conversion of Volume Measurements Convert 7 cups 5 oz. into ounces. Method – ( 7 x 8 ) + 5 = 61 oz. Convert 24 Tbsp. into ounces – Method 1 24 / 2 = 12 oz. – Method 2 24 x.5 = 12 oz.
Converting Portion Size Example Original Recipe Yield is 10 portion at 12 oz. Desired Recipe Yield is for 32 portion at 10 oz. Convert recipe to like units (oz.) – 10 x 12 = 120 oz (old) – 32 x 10 = 320 oz (new) 320 / 120 = 2.66
Recipe Conversion New Desired Yield Old Yield (Original) Conversion Factor Original recipe made 2 gallons of soup New recipe makes 4 gallons of soup
Yields 150 guest 9 oz. Cooked Prime Rib How much do you cook?
One Prime Rib = 20 lb. 4 oz. AP After trimming and cooking = 11 lb. 2 oz. EP Step 1 Convert to oz. 20 x 16 = = x 16 = = 178 Yields
rd to.55 AP EP Started with Ended with
150 x 9oz. = 1350 oz. of EP oz. AP (rd) Yield Factor Use this formula : EP / Yield Factor = AP
The Real Answer 2455 oz. AP lbs 7 oz Number of oz. in lb. This is how much you need to Fire
