OTHER CONVERSION FACTORS AND CONSTANTS

Weight/Mass

16 ounces = 1 pound

1 kilogram = 2.2 pounds

454 grams = 1 pound

1 ton = 2000 pounds

Volume

1 liter = 1.0567 quarts

1 mL = 1 cm3

1 gallon = 3.78 liters

1 gallon = 4 quarts = 128 fluid ounces

1 quart = 2 pints = 32 fluid ounces

1 pint = 2 cups = 16 fluid ounces

Length/Distance

1 inch = 2.54 centimeters

1 mile = 5280 feet = 1.609 kilometers

1 yard = 3 feet = 36 inches = 0.9144 meters

1 meter = 39.37 inches = 3.281 feet = 1.094 yards

1 kilometer = 1094 yards = 0.6215 miles

Density of Water: 1.00 g/mL

Energy: 1 cal = 4.184 J

Time

1 year = 365 days = 12 months = 52 weeks

1 day = 24 hours

1 hour = 60 minutes

1 minute = 60 seconds

Temperature

Kelvins = ºC + 273

Pressure Units: 1 atm = 760 mmHg = 760 torr = 101.3 kPa = 14.7 psi = 29.92 inches Hg

Avogadro’s Number (NA) = 6.02 x 1023 items / mole

L ⋅ atm L ⋅ kPa mmHg L ⋅ torr

Ideal Gas Constant (R) = 0.0821 = 8.314 = 62.4 = 62.4
