How to convert Atmospheres to Pascals

Pressure units vary by field: meteorologists use bar and pascals, tire gauges use PSI or bar, and scientists reference standard atmospheres. One standard atmosphere is exactly 101,325 pascals.

All units convert through the pascal, the SI unit equal to one newton per square meter. One bar is exactly 100,000 Pa and one PSI is about 6,894.76 Pa.

Formula

atm × 101,325 = Pa

Multiply your atmospheres value by 101,325 to get pascals. For the reverse, divide by the same factor.
