## How the conversion works

The relationship is atm = Pa × 0.000009869233. Both units measure pressure, so the conversion is a fixed factor that never changes.

## Common questions

### How many standard atmospheres are in one pascal?

One pascal equals 0.000009869 standard atmospheres. atm = Pa × 0.000009869233.

### How do you convert pascals to standard atmospheres?

Use atm = Pa × 0.000009869233. So 10 Pa is 0.00009869 atm.

### How many pascals are in one standard atmosphere?

One standard atmosphere equals 101,325 pascals, which is the reverse of the conversion above.
