1 cup = 8 fl. oz. = ? pt. = 16 tablespoons = 236.6 ml 1 milliliter (ml) = 1 cm3 = 0.034 fl.oz. = 0.002 pts
1 US fluid ounce = 29.57 ml = 2 tablespoons = 6 tsp. = 0.03125 qt
1 teaspoon = 4.93 ml = 0.1667 fl. oz. = 80 drops
Temperature Equivalents degrees Centigrade = (?F-32)x5/9 degrees Fahrenheit = (?Cx9/5)+32
Pressure Equivalents 1 lb per square inch (PSI) = 6.9 kilopascal (kPa)
1 PSI = 2.31 feet head of water 1 atm = 760 mmHg = 1.013 x 105 Pa = 1.013 bar = 14.70 psi 1 mmHg = 133.32 Pa = 0.133 kPa = 133,333 mPa 1Pa = 10-3 kPa = 10-6 mPa 1mPa = 103 kPa = 106 Pa 1kPa = 1cb = 0.001MPa =10 cm H20 = 10 mbar = 0.01 bar = 1J/kg = 0.0099 atm. = 0.145 psi
Length Equivalents centimeter (cm) = 0.3937 inch = 0.01 m = 0.03281 ft. kilometer = 0.621 statute mile = 1000 meters = 100,000 cm = 3281 ft = 39,370 in. inch = 2.54 cm = 25.4 mm = 0.0254 m = 0.08333 ft. yard = 0.9144 meters = 3 feet = 36 inches = 91.44 cm

Weight Equivalents 1 ton (US) = 2000 lb = 0.907 metric tons = 907.2 kg
1 metric ton = 106 g = 1000 kg = 2205 lb
1 lb = 16 oz = 453.6 grams (g) = 0.4536 kg
1 oz (weight) = 28.35 g = 0.0625 lb
1 gram = 1000 mg = 0.0353 oz = 0.001 kg = 0.002205 lb
milligrams (mg) = 0.001 grams
1 kilogram (kg) = 1000 grams = 35.3 oz = 2.205 lbs
microgram (? g) = 10-6 grams = 0.001 mg
nanogram (ng) = 10-9 grams = 0.001 micrograms (:g)
picogram = 10-12 grams
1 ppm = 0.0001% = 1 mg/kg = 1 mg/L = 1 ? g/g = 1?l/l = 1?g/mL = 0.379 g in 100 gal water = 8.34 x 10-6 lb/gal = 0.013 fl oz in 100 gal
10 ppm = 0.001% = 10 mg/L
100 ppm = 0.01% = 100 mg/L 1000 ppm = 1 mg/g = 0.1% = 1000 mg/L
1 ppb = 1 ?g/kg = 1 ?g/L = 1 ng/mL = 1 ng/1,000,000,000
1 ppt = 1 picogram/g
1% = 10,000 ppm = 10g/L = 1g/100ml = 10g/kg = 1.33 oz by weight/gal water = 8.34 lbs/100 gal water
1% (v/v) = 1.28 fl.oz./gal = 1 gal/100 gal
