**Definitions:**

**Pascal** (abbreviations: **Pa, or N/m2**): is the SI derived unit of pressure used to quantify internal pressure, stress, Young's modulus and ultimate tensile strength. It is one newton per square meter. It is named after the French polymath Blaise Pascal.

**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 Pascals to Bars

*Example: How many Bars are equivalent to 2.21 pascals?*

As;

1 pascals = 1.0E-5 Bars

2.21 pascals = Y Bars

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

Y equals 2.21 times 1.0E-5 over 1

(i.e.) Y = 2.21 * 1.0E-5 / 1 = 2.21E-5 Bars

Answer is: 2.21E-5 Bars are equivalent to 2.21 pascals.
