Millimeter Of Mercury (abbreviations: mm Hg, or mmHg): is a manometric unit of pressure, equal to 133.322387415 pascals. It is the extra pressure generated by a column of mercury of one millimeter high.
Pound Per Square Foot (abbreviations: psf, or lb/ft2): is a British (Imperial) and American pressure unit which is directly related to the psi pressure unit by a factor of 144 (1 sq ft = 12 in x 12 in = 144 sq in). Where, 1 pound per square foot equals 47.8803 pascals.
How to Convert Millimeters Of Mercury to Pounds Per Square Feet
Example: How many pounds per square feet are equivalent to 66 Millimeters of Mercury?
As;
1 Millimeters of Mercury = 2.7845297820991 pounds per square feet
66 Millimeters of Mercury = Y pounds per square feet
Assuming Y is the answer, and by criss-cross principle;
Y equals 66 times 2.7845297820991 over 1
(i.e.) Y = 66 * 2.7845297820991 / 1 = 183.77896561854 pounds per square feet
Answer is: 183.77896561854 pounds per square feet are equivalent to 66 Millimeters of Mercury.
