CONVERSION FACTORS

TEMPERATURE: If F and C denote readings on the Fahrenheit and centigrade standard scales, respectively, for the same, then

C = 5/9* (F - 32) F = (9/5)* C + 32

Some common reference points are:

0°C = 32°F, 22°C = 71.6°F, 37°C = 98.6°F, and 100°C = 212°F.

CONVERSION TABLE FOR MEDICATED FEEDS:

1 Pound = 453.6 Grams 1 Milligram = 1,000 Micrograms

1 Gram = 0.0022 Pounds 1 Microgram = 0.001 Milligrams

1 Gram = 1,000 Milligrams 1 Microgram Per Gram = 1 Part Per Million

1 Gram = 1,000,000 Micrograms

1 Kilogram = 1,000 Grams 1 Part Per Million (PPM) = 0.454 Mg/Lb.

1 Kilogram = 2.205 Pounds 1 Part Per Million (PPm) = 0.907 Grams

1 Milligram = 0.001 Grams Per Ton

HOUSEHOLD MEASURES:

1 teaspoon (tsp) = 5cc = 1 fl dram

1 dessertspoon = 8cc = 2 fl drams

1 tablespoon (tbsp) = 15cc = 1/2 fl ounce

1 teacup = 120cc = 4 fl ounces

1 tumbler = 240cc = 8 fl ounces = 1/2 pint

8 pints = 4 quarts = 1 gallon = 128 fluid ounces
