Measurement Information
Measures of Pressure
1 Pound Per Square Inch = 144 Pounds Per Square Foot = 0.068 Atmosphere = 2.042 Inches of Mercury at 62°F = 27.7 Inches
of Water at 62°F = 2.31 Feet of Water at 62°F.
1 Atmosphere = 30 Inches of Mercury at 62°F = 14.7 Pounds Per Square Inch = 2116.3 Pounds Per Square Foot = 33.95 Feet of
Water at 62°F.
1 Foot of Water at 62°F = 62.355 Pounds Per Square Foot = 0.433 Pounds Per Square Inch.
1 Inch of Mercury at 62°F = 1.132 Feet of Water = 13.58 Inches of Water = 0.491 Pounds Per Square Inch.
Column of Water 12 Inches High, 1 Inch in Diameter = .341 Pounds
If temperature is kept constant, the volume of a given mass of gas is inversely proportional to the pressure which is exerted upon
it.
Circumference of a Circle
Circumference = 2 r = d = 3.14159 d
Area = r2 = = .78539d2 d2
4
Right Cylinder
r = radius
h = length
Volume = r2 h
Surface Area = 2 r (r + h)
If end planes are parallel but not at 90° to h, the same
formulas apply, but a slice at 90° through the cylinder must be
used to determine r.
Weight Conversion Constants
Grams x .03527 = Ounces (Avd.)
Grams x .033818 = Fluid Ounces (Water)
