🌬️ About This Conversion

Converting Atmospheres (atm) to PSI (psi) is a standard pressure conversion used daily in science, engineering, travel, and everyday life. This conversion bridges the mixed and imperial systems — one of the most common cross-system unit lookups worldwide.

From Unit Atmospheres Symbol: atm · mixed system

To Unit PSI Symbol: psi · imperial system

Category Pressure Measurement type

Precision Up to 8 decimal places Scientific grade

🔢 Conversion Formula

PSI = Atmospheres × 14.696024

1 Atmospheres = 14.696024 PSI. Multiply any Atmospheres value by this factor to get PSI.

📊 Quick Reference Table

Atmospheres		PSI
0.1 atm	→	1.4696 psi
0.25 atm	→	3.67401 psi
0.5 atm	→	7.34801 psi
1 atm	→	14.696 psi
2 atm	→	29.392 psi
5 atm	→	73.4801 psi
10 atm	→	146.96 psi
25 atm	→	367.401 psi

🌍 When You'd Use This Conversion

Used in chemistry, diving, and industrial gas cylinders to express pressure in US customary units.

Country usage: Atmospheres are used in chemistry and diving worldwide. PSI is used in US engineering and gas cylinder ratings.

📌 Real-World Reference Values

1 atm = 14.696 psi — sea level air pressure
1 atm = 101,325 Pa = 1.01325 bar
10 atm = 146.96 psi — scuba tank working pressure (entry level)
200 atm = 2,939 psi — full scuba cylinder pressure

⚠️ Common Mistake

Confusing standard atmosphere (atm) with technical atmosphere (at = 98,066 Pa) — they differ by 0.13%.

📋 Common Use Cases

Tyre (tire) pressure checks and inflation
Blood pressure readings and medical diagnostics
Barometric weather pressure forecasting
Hydraulic and pneumatic engineering systems
Scuba diving depth and decompression calculations

💡 Did You Know?

1 standard atmosphere (atm) is defined as 101,325 Pa — the average air pressure at sea level. At the peak of Mount Everest (8,849 m), atmospheric pressure drops to roughly 0.33 atm, making each breath deliver one-third the oxygen.
