Facts and Figures about Water

Some of water's physical properties:

◆ Weight: 62.416 pounds/cubic foot at 32°F; 1,000 kilograms/cubic meter
◆ Weight: 61.998 pounds/cubic foot at 100°F; 993 kilograms/cubic meter
◆ Weight: 8.33 pounds/gallon; 1 kilogram/liter
◆ Density: 1 gram/cubic centimeter (cc) at 39.2°F, 0.95865 gram/cc at 212°F

Some water volume comparisons:

◆ 1 gallon = 4 quarts = 8 pints = 128 fluid ounces = 3.7854 liters
◆ 1 liter = 0.2642 gallons = 1.0568 quart
◆ 1 million gallons = 3.069 acre-feet = 133,685.64 cubic feet

Water Flow Rates:

◆ 1 cubic foot/second (cfs) = 449 gallons/minute = 0.646 million gallons/day = 1.98 acre-feet/day
