How to Convert Gas Pressure Units Easily

TL;DR

To convert gas pressure units, use the following key relationships: 1 atm equals 760 torr, 14.7 psi, and 101.3 kPa. For example, to convert torr to atm, divide the torr value by 760. Similarly, to convert psi to atm, divide by 14.7. Understanding these conversions is essential for solving gas law problems.
