Special units of conversion

OIL:

1 barrel of oil= 42 gallons;
1 US ton (= short ton) of oil is roghly 6.3 barrels or 264.6 gallons (but varies with density of the oil; a No. 2 fuel oil might equal 272 gallons whereas No. 6 fuel oil might equal 248 gallons)

WATER:

1 gallon = 8.33 pounds. 1 cubic ft = 7.48 ga
1 cubic m = 258.1 ga

2002 Addendum

multiply cubic foot per second (ft 3 /s) by 0.02832 to obtain cubic meter per second
multiply cubic foot per second per square mile [(ft 3 /s)mi 2 ] by 0.01093 to obtain cubic meter per second per square kilometer
multiply million gallons per day (Mgal/d) by 0.04381 to obtain cubic meter per second
Temperature in degrees Fahrenheit (°F) can be converted to degrees Celsius (°C) as follows: °C = 5/9 (°F - 32).
