**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 58.03 Millimeters of Mercury?*

As;

1 Millimeters of Mercury = 2.7845297820991 pounds per square feet

58.03 Millimeters of Mercury = Y pounds per square feet

Assuming Y is the answer, and by criss-cross principle;

Y equals 58.03 times 2.7845297820991 over 1

(i.e.) Y = 58.03 * 2.7845297820991 / 1 = 161.58626325521 pounds per square feet

Answer is: 161.58626325521 pounds per square feet are equivalent to 58.03 Millimeters of Mercury.
