Pound per square inch is a pressure unit based on one pound-force applied over one square inch.
Psi became common in US customary pressure measurement and remains widely used on gauges and equipment labels.
psi is used for tires, compressors, hydraulics, pneumatics, pressure gauges, industrial equipment, and service documentation.
A standard atmosphere is a pressure unit defined as exactly 101,325 pascals.
The atmosphere unit became useful as a reference for average sea-level air pressure in science and education.
atm is used in chemistry, gas laws, diving references, laboratory work, classroom problems, and pressure comparisons.
Mathematically, standard atmosphere (atm) = pound per square inch (psi) converted with the formula below.
1 psi = 0.068046 atm
1 atm = 14.695949 psi
Formula: value × 0.0680459639099
Example: 15 psi = 1.020689 atm
Precision note: Use 1 atm = 14.69594878 psi. Preserve decimals when comparing values near atmospheric pressure.
1 psi = 0.068046 atm
1 atm = 14.695949 psi
