**Definitions:**

**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.

**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 Bars to Pounds Per Square Feet

*Example: How many pounds per square feet are equivalent to 67.21 Bars?*

As;

1 Bars = 2088.4707766213 pounds per square feet

67.21 Bars = Y pounds per square feet

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

Y equals 67.21 times 2088.4707766213 over 1

(i.e.) Y = 67.21 * 2088.4707766213 / 1 = 140366.12089672 pounds per square feet

Answer is: 140366.12089672 pounds per square feet are equivalent to 67.21 Bars.
