- 1 atm = 101325 Pa
- 1 × 101325 = 101325 Pa
How to convert standard atmospheres to pascals
1 atm = 101,325 Pa, so multiply by 101,325 to go from standard atmospheres to pascals. Going the other way, 1 Pa = 9.86923266716 × 10⁻⁶ atm.
Pa = atm × 101,325 atm = Pa × 9.86923266716
Worked example:
1 atm = 101325 Pa 5 × 101325 = 506625 Pa
