Formula: PSI = atm × 14.696

What is 1 atm?

1 atmosphere (atm) is the average air pressure at sea level: 14.696 PSI, 101,325 Pa, 1.01325 bar, or 760 mmHg. It is used as a reference in chemistry, physics, and diving.

Frequently Asked Questions

What is normal tire pressure in atm?

Typical car tire pressure is 32-35 PSI = about 2.2-2.4 atm (gauge) or 3.2-3.4 atm (absolute).

How many atm can a human survive?

Trained divers can tolerate about 6 atm (60 meters depth). Saturation divers have worked at over 30 atm with special gas mixtures.
