Welcome Culinary Math – CHRM 0950
Agenda • Review Chapter One Problems • Chapter 2 & 3 • Next week
Units of Measure Metric Measures Chapters 2-3
Learning Objectives • List the names and abbreviations of the units of measure most commonly used in the foodservice industry • Demonstrate your understanding of the relative sizes of the measuring tools used in the foodservice industry • Recall the equivalents of volume measures without references • Recall the equivalents of weight measures without references • Explain the difference between weight and volume measurements • Define a fluid ounce and explain how it differs from an ounce
Volume- the space filled by a liquid, gas or solid. - Tesapoon (Tsp.) Tablespoon (Tblsp.) Fluid Ounce (Fl. oz.) Cup (c.) Pint (pt.) Quart (qt.) Gallon 9gal.) Weight- the heaviness of a substance. Ounce (oz.) Pound (# or lb.) Volume vs. Weight
Volume vs. Weight • Liquids are measured by volume • Solids and dry ingredients are measured by weight. • Liquids can be accurately measured by weight. • Some small critical dry ingredients may be measured by volume.
Volume 3 tsp. = 1 Tbsp. 2 Tbsp. = 1 fl. oz. 8 fl. oz. = 1 cup 2 cups = 1 pint 2 pints = 1 quart 4 quarts = 1 gallon Weight 16 oz. = 1 pound Equivalents
1 cup = 16 Tbsp. 1 cup = 48 tsp. 1 pt. = 16 fl. Oz. 1 qt. = 32 fl. Oz. 1 gal. = 4 quarts 1 gal. = 8 pints 1 gal. = 16 cups 1 gal. = 128 fl. Oz. ½ gal. = 64 fl. Oz. More Equivalents

Metric System • Most common used system in the world. (Except for the United States) • Why should you learn it? • Working in other countries. • Working with recipes/formulas from other countries. • Measuring Wine & Spirits. • When purchasing ingredients from overseas.
Liter – L (volume) Gram – g (weight) PREFIXES Kilo = 1,000 Deka = 10 Deci = .1 (1/10) Centi = .01 (1/100) Milli = .001 (1/1000) Metric Units of Measure
GRAM Kilogram = 1000 grams Dekagram = 10 grams Decigram = .1 grams Centigram = .01 grams Milligram = .001 gram LITER Kiloliter = 1000 Liters Dekaliter = 10 Liters Deciliter = .1 Liter Centiliter = .01 Liter Milliliter = .001 Liter Metric Prefixes
Metric Equivalents • 1 oz. = 28.35 grams • 1 kilogram = 2.21 pounds • 1 liter = 33.8 fl. oz.
