Convert Atmospheres to pascals
1 atmosphere = 101,325 pascals · Pa = atm × 101,325
When you need this conversion
This conversion goes from atmospheres, pressure relative to sea level, used in diving and chemistry, to pascals, the SI pressure unit used in engineering. Both measure the same physical quantity, so the conversion is exact — the difference is which unit your source, tool, or region happens to use.
