Standard Atmosphere to PSI Conversion - Accurate atm ⇄ psi Converter
Convert between standard atmospheres (atm) and pounds per square inch (PSI) with precision using standard pressure measurements
Pressure is a vital measurement in physics, meteorology, engineering, and daily life. Two common units used to measure pressure are standard atmosphere (atm) and pounds per square inch (psi). While the atmosphere is often used in scientific fields like chemistry and physics, psi is more practical in industries like automotive, hydraulics, and aerospace.

What is a Standard Atmosphere (atm)?
The standard atmosphere (atm) is a unit of pressure defined as the mean atmospheric pressure at sea level on Earth.
Key Facts About Atmosphere
- Exact value: 1 atm = 101,325 Pa = 14.696 psi.
- Abbreviation: atm.
- Usage: Chemistry (gas laws), physics, meteorology, and aviation.
- Relationship: 1 atm ≈ 1.013 bar.
What is PSI (pounds per square inch)?
PSI is an imperial unit of pressure, representing the force of one pound-force applied over one square inch of area.
Key Facts About PSI
- Exact value: 1 psi = 6,894.76 Pa.
- Abbreviation: psi.
- Usage: Tire pressure, hydraulics, engineering, aerospace.
- Relationship: 14.696 psi = 1 atm.
Standard Atmosphere to PSI Conversion Formula
Formula:
psi = atm × 14.696
Standard Atmosphere to PSI Conversion Example
- 1 atm to psi
Step 1: Formula = psi = atm × 14.696
Step 2: Substitute = 1 × 14.696
Step 3: Result = 14.696 psi
- 2 atm to psi
Step 1: psi = atm × 14.696
Step 2: Substitute = 2 × 14.696
Step 3: Result = 29.392 psi
- 5 atm to psi
Step 1: psi = atm × 14.696
Step 2: Substitute = 5 × 14.696
Step 3: Result = 73.48 psi
PSI to Standard Atmosphere Conversion Formula
Formula:
atm = psi ÷ 14.696
PSI to Standard Atmosphere Conversion Example
- 14.696 psi to atm
Step 1: Formula = atm = psi ÷ 14.696
Step 2: Substitute = 14.696 ÷ 14.696
Step 3: Result = 1 atm
- 29.392 psi to atm
Step 1: atm = psi ÷ 14.696
Step 2: Substitute = 29.392 ÷ 14.696
Step 3: Result = 2 atm
- 73.48 psi to atm
Step 1: atm = psi ÷ 14.696
Step 2: Substitute = 73.48 ÷ 14.696
Step 3: Result = 5 atm
Applications of Atmosphere and PSI Conversion
- Chemistry: Gas laws like Boyle’s and Charles’s law use atm but sometimes converted to psi for engineering.
- Automotive: Tire pressures are usually measured in psi but can be compared with atm for standards.
- Aerospace & Aviation: Cabin pressures are calculated using atm and psi.
- Meteorology: Atmospheric readings often switch between atm, bar, and psi.
- Engineering: Hydraulics, pipelines, and industrial machines require accurate pressure conversions.
