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.
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.
How to Convert Pounds Per Square Feet to Millimeters Of Mercury
Example: How many Millimeters of Mercury are equivalent to 51.53 pounds per square feet?
As;
1 pounds per square feet = 0.35912706210891 Millimeters of Mercury
51.53 pounds per square feet = Y Millimeters of Mercury
Assuming Y is the answer, and by criss-cross principle;
Y equals 51.53 times 0.35912706210891 over 1
(i.e.) Y = 51.53 * 0.35912706210891 / 1 = 18.505817510472 Millimeters of Mercury
Answer is: 18.505817510472 Millimeters of Mercury are equivalent to 51.53 pounds per square feet.
