**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 Inch** (abbreviations: **psi, or lb/in2**): is a unit of pressure or of stress based on avoirdupois units. It is the pressure resulting from a force of one pound-force applied to an area of one square inch.

## How to Convert Bars to Pounds Per Square Inches

*Example: How many pounds per square inches are equivalent to 32.28 Bars?*

As;

1 Bars = 14.50326 pounds per square inches

32.28 Bars = Y pounds per square inches

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

Y equals 32.28 times 14.50326 over 1

(i.e.) Y = 32.28 * 14.50326 / 1 = 468.1652328 pounds per square inches

Answer is: 468.1652328 pounds per square inches are equivalent to 32.28 Bars.
