**Definitions:**

**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.

**Bar** (abbreviation: **bar**): is a metric (still not approved by the International System of Units, SI) unit of pressure. It is exactly equal to 100,000 Pa and slightly lower than the current average atmospheric pressure on Earth, at sea level.

## How to Convert Pounds Per Square Feet to Bars

*Example: How many Bars are equivalent to 74.38 pounds per square feet?*

As;

1 pounds per square feet = 0.00047881924477669 Bars

74.38 pounds per square feet = Y Bars

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

Y equals 74.38 times 0.00047881924477669 over 1

(i.e.) Y = 74.38 * 0.00047881924477669 / 1 = 0.03561457542649 Bars

Answer is: 0.03561457542649 Bars are equivalent to 74.38 pounds per square feet.
