Fluid Measurement Conversion, Fluid calculations, Fluid considerations

Fluid measurement conversion speaks to fluid calculations and fluid considerations are equivalents which are in common use in the hydraulics industry of today.

Exact equivalents

1 US gallon: = 231 cubic inches = 4 quarts or 8 pints = 128 ounces liquid = 133.37 ounces weight = 8.3356 pounds = 3.785 litres

1 Imperial gallon = 1.2 US gallons

1 Litre = 0.2642 US gallons

1 Cubic foot: = 7.48 gallons = 1728 cubic inches = 62.4 pounds (water)

1 Cu ft water weighs 62.4 lbs

1 Bar at sea level: = 14.504 PSI = 0.98692 atmosphere = 33.6 foot water column = 41 foot oil column

Approx ½ PSI decrease each 1000 feet of elevation.

1”Hg = 0.490 PSI = 1.131 ft water

1 Horsepower: = 33,000 ft lbs per minute = 550 ft lbs per second = 42.4 BTU per minute = 2545 BTU per hour = 746 watts or 0.746 kw

1 PSI: = 2.0416 “Hg = 27.7” water = 0.0689 bar

1 Atmosphere: = 1.013 bar = 29.921 “Hg = 14.696 PSI = 760 mm Hg

1 Foot water column = 0.432 PSI

1 Foot oil column = 0.354 PSI

1 Barrel oil = 42 gallons

1 Micro-meter: = 0.000001 meter (micron) = 0.001 centimeter = 0.00004 inch

25 Micro-meters = 0.001 inch

Approximate Equivalents

1 Pint = 2 cups = 32 tablespoons = 96 teaspoons = 16 fl oz = 1 lb

1 Quart = 4 cups = 2 pints = 32 fluid ounces = 2 pounds

1 Gallon = 16 cups = 4 quarts = 8 pints = 128 fluid ounces = 231 cubic inches

1 Cup = 16 tablespoons = 48 teaspoons

1 Tablespoon = 3 tsp = ½ fluid oz

1 Fluid oz (volume) = 600 drops hydraulic oil

1 Cubic inch = 330 drops (oil)
