Atmosphere to Pascal (atm to Pa)
Result
101,325 Pascal
Formula
Pa = atm × 101,325
1 atm = 101,325 Pa, and 1 Pa = 0.000009869233 atm.
The pascal is one newton per square metre. The bar is exactly 100,000 Pa, the standard atmosphere exactly 101,325 Pa, the torr exactly 1/760 atm, and psi is one pound-force per square inch (6,894.757 Pa).
Worked examples
- 0.5 atm × 101,325 = 50,662.5 Pa
- 1 atm × 101,325 = 101,325 Pa
- 2 atm × 101,325 = 202,650 Pa
- 10 atm × 101,325 = 1,013,250 Pa
Things to know about atm to Pa
- One standard atmosphere is exactly 101,325 Pa, or 1,013.25 hPa on a weather map.
- Every 10 m of seawater adds roughly one atmosphere of pressure.
