Convert Pascals to Atmospheres

The Pa-to-atm conversion appears often when working with pressure data across different unit systems. Pressure conversions appear in tire inflation, weather forecasting, scuba diving, and industrial engineering across pascals, bar, psi, and mmHg.

To convert, multiply the pascals value by 9.8692e-6. Written as an equation: atm = Pa × 9.8692e-6.

One pascals equals approximately 0.00001 atm. This means you can multiply any Pa value by 0.00001 to get the equivalent in atm.

Worked example: 10 Pa = 0.000099 atm. Enter your own value in the converter above for instant results.

Common mistake: Tire pressure may be listed in psi, bar, or kPa depending on your gauge or vehicle manual — always match the unit your manufacturer specifies.
