Convert PSI to Atmosphere (psi to atm)
Convert PSI (Pounds per Square Inch) to Standard Atmospheres (atm). When dealing with high-pressure systems like gas cylinders or hydraulic lines, converting to 'atmospheres' helps visualize the immense forces involved relative to the air pressure we experience every day at sea level.
Divide PSI by roughly 14.7. For example, 100 psi ÷ 14.6959 ≈ 6.8 atm.
