**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.

**Atmosphere** (abbreviation: **atm**): is a unit of standard pressure, equal to 101325 Pa, or 1.01325 bar.

## How to Convert Pascals to Atmospheres

*Example: How many Atmospheres are equivalent to 8.99 pascals?*

As;

1 pascals = 9.8692326671601E-6 Atmospheres

8.99 pascals = Y Atmospheres

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

Y equals 8.99 times 9.8692326671601E-6 over 1

(i.e.) Y = 8.99 * 9.8692326671601E-6 / 1 = 8.872440167777E-5 Atmospheres

Answer is: 8.872440167777E-5 Atmospheres are equivalent to 8.99 pascals.
