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

ExampleOriginal 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
