Conversion Factors
1 acre = 43,560 sq ft
1 acre foot = 7758.0 barrels
1 atmosphere = 760 mm Hg = 14.696 psia = 29.91 in. Hg
1 atmosphere - 1.0133 bars = 33.899 ft. H 2 0
1 barrel (oil) = 42 gal = 5.6146 cu ft
1 barrel (water) = 350 lb at 60°F
1 barrel per day = 1.84 cu cm per second
1 Btu = 778.26 ft-lb
1 centi poise x 2.42 = lb mass/(ft) (hr), viscosity
1 centipoise x 0.000672 = lb mass/(ft) (sec), viscosity
1 cubic foot = 28,317 cu cm = 7.4805 gal
Density of water at 60°F = 0.999 gram/cu cm = 62.367 Ib/cu ft
- 8.337 lb/gal
1 gallon = 231 cu in. = 3,785.4 cu cm = 0.13368 cu ft
1 horsepower-hour - 0.7457 kwhr = 2544.5 Btu
1 horsepower = 550 ft-lb/sec = 745.7 watts
1 inch = 2.54 cm
1 meter = 100 cm = 1,000 mm = 10 microns = 10 angstroms (A)
