Atmosphere to PSI Converter
Pressure · unit-converter
Convert Atmosphere to PSI with a fixed input and output unit, step-by-step formula line, and reference tables. All calculations bridge through pascal with fixed definitions (standard atmosphere = 101,325 Pa; torr and mmHg = atm/760; plus industrial/manometer units like kgf/cm², inHg, inH2O, and mmH2O).
About Atmosphere
The standard atmosphere (atm) is defined as exactly 101,325 Pa. It links legacy chemistry and physics problems to SI.
About PSI
Pounds-force per square inch (PSI) is common for tires, hydraulics, and US industrial equipment.
How to convert atmosphere to psi
1 atmosphere equals 14.69594877551422 psi in this tool (via pascal):
1 atm = (101325 Pa ÷ 6894.757293168 Pa) psi = 14.69594877551422 psi
Each atmosphere carries 101325 Pa and each psi 6894.757293168 Pa, so one atm equals 101325 ÷ 6894.757293168 psi.
Let p(atm) be pressure in Atmosphere (atm), and p(psi) in PSI (psi). Then:
p(psi) = p(atm) × (101325 / 6894.757293168)
Equivalently, divide by how many atm fit into one psi (Pa per psi divided by Pa per atm):
p(psi) = p(atm) ÷ 0.06804596390987416
Examples
Example #1: Convert 1 atm to psi
1 atm = 1 atm × (101325/6894.757293168) psi = 14.6959487755 psi
1 atm = 1 atm ÷ 0.06804596390987416 = 14.6959487755 psi
1 atm × (101,325/6,894.757293168) = 14.695949 psi
Example #2: Convert 10 atm to psi
10 atm = 10 atm × (101325/6894.757293168) psi = 146.959487755 psi
10 atm = 10 atm ÷ 0.06804596390987416 = 146.959487755 psi
10 atm × (101,325/6,894.757293168) = 146.959488 psi
Summary
To convert Atmosphere to PSI, multiply the value in atm by (101325 Pa per atm) / (6894.757293168 Pa per psi). Equivalently: value_psi = value_atm × (101325 / 6894.757293168). Numerically, 1 atm equals 14.69594877551422 psi.
Relationship context
Both Atmosphere and PSI are converted by fixed multiples of the pascal. Multiplying by (Pa per atm) ÷ (Pa per psi) gives the same result as passing through pascal, keeping bar, atm, PSI, kPa, hPa, torr, and mmHg consistent on the hub.
