**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.

**Kilopound Per Square Inch** (abbreviations: **ksi, or kips/in2**): is a unit of pressure or of stress based on avoirdupois units. It is the pressure resulting from a force of one kilopound-force applied to an area of one square inch.

## How to Convert Bars to Kilopounds Per Square Inches

*Example: How many kilopounds per square inches are equivalent to 57.1 Bars?*

As;

1 Bars = 0.01450326 kilopounds per square inches

57.1 Bars = Y kilopounds per square inches

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

Y equals 57.1 times 0.01450326 over 1

(i.e.) Y = 57.1 * 0.01450326 / 1 = 0.828136146 kilopounds per square inches

Answer is: 0.828136146 kilopounds per square inches are equivalent to 57.1 Bars.
