Conversions/Equations For Exam calculations, express numbers out to two decimal places. For example 1.33333333333333333333 = 1.33 and 1.86432 = 1.84. For our purposes, it doesn’t really matter how you round off numbers with a 5 in the third decimal place. I usually round up, when I am in a good mood (3.33 = 3.34). 1 ppm = 1 mg/kg or 1 µg/g (solid) or 1 mg/L (liquid)1% = 10,000 ppm = 10 mg/g (solid) = 10 mg/mL (liquid)1 ppm = 0.0001% DRY:1 oz = 28.35 g1 cup = 8 oz1 teaspoon = 5 g1 tablespoon = 15 g LIQUID:1 fluid oz = 29.6 mL1 quart = 0.946 L1 gallon = 3,785 mL = 3.785 L1 cup = 8 fluid oz = 237 mL1 teaspoon = 5 mL1 tablespoon = 15 mL Conversion of lb to oz by multiplying by 16Conversion of kg to lb by multiplying by 2.20Conversion of lb to kg by multiplying by 0.454Conversion of oz/kg BW to oz/lb BW by multiplying the number of ounces by 0.454Conversion of Crude Protein Equivalent as Urea to % Urea by dividing the Crude Protein Equivalent as Urea (%) by 2.92Conversion of grams/ton to ppm by remembering that 1 g/ton = 1.1 ppm and that 100g/ton = 110 ppmConversion of ppm of A in feed to dosage of A as mg/kg BW: mg A/kg BW = Level of A in feed/medication/bait (ppm of A or mg of A/kg of feed/medication/bait) X kg feed/medication/bait consumed                                                                                                                    kg BW
