Frequently asked questions

How do I convert atmospheres to pascals?

To convert atmospheres to pascals, multiply the value by 101,325: Pa = atm × 101,325. For example 2.5 atm = 253,312.5 Pa.

What is 1 atm in pascals?

1 atm = 101,325 Pa. The other way round, 1 Pa = 0.000009869232667 atm.

How exact is the result?

The converter uses the official definitions of both units and shows up to 10 significant digits; choose 0–6 decimals to round. Both units are defined exactly in terms of each other, so the factor itself is exact.

Can I convert other units of pressure here?
