How to Convert PSI to Atmospheres
Pressure conversion is important in engineering, meteorology, medicine, and automotive maintenance. Whether you're checking tire pressure, reading a weather barometer, or working with hydraulic systems, converting between PSI and Atmospheres is a practical skill.
Conversion Formula
Pressure is force per unit area. The factor 0.0680460 converts between the specific force/area definitions of psi and atm. The Pascal (1 N/m²) is the SI standard, with other units defined relative to it.

Frequently Asked Questions
How do I convert PSI to Atmospheres?
Multiply the value in PSI by 0.0680460. For example, 14.7 psi = 1.00028 atm.
What is standard atmospheric pressure?
Standard atmospheric pressure at sea level is 1 atm = 101,325 Pa = 1.01325 bar = 14.696 psi = 760 mmHg. This is the baseline for many pressure measurements.
What is the difference between PSI and bar?
PSI (pounds per square inch) is used primarily in the US and UK, while bar is the metric standard. 1 bar ≈ 14.504 psi. Tire pressures, for example, may be listed in either unit depending on your country.
What is the formula for PSI to Atmospheres?
atm = psi × 0.0680460. This conversion factor is derived from the precise definitions of each pressure unit.
