atm to psi converter
1 atm = 14.6959 psi
And 1 psi = 0.068046 atm. Standard atmosphere to pounds per square inch.
Formula
psi = atm × 14.6959
A reading of 15 atm is 15 × 14.6959 = 220.439 psi.

About these units
atm (standard atmosphere): Defined as 101,325 Pa, roughly sea-level air pressure.
psi (pounds per square inch): US customary pressure: tires, compressed air, hydraulics and water supply.
Gauge pressure (psig, barg) is measured relative to the surrounding atmosphere; absolute pressure (psia, bara) is relative to vacuum. Converting units never changes that reference: absolute = gauge + about 14.696 psi (1.01325 bar) at sea level. Stress uses the same units: 1 MPa = 1 N/mm².
