Instant, two-way conversion across common engineering units.
1 atm = 14.695949 psi(Atmosphere → Pounds per square inch)
To convert standard atmospheres to pounds per square inch, multiply the value by 14.695949. Pressure conversions link structural loading, material strength grades and mechanical system ratings across metric and US practice.
The standard atmosphere (atm) represents average air pressure at sea level.
Pounds per square inch (psi) is the pressure unit of US customary engineering.
1 atm equals 14.695949 psi.
Multiply the value by 14.695949. For example, 10 atm equals 146.95949 psi.
1 psi equals 0.068045964 atm. The converter above works in both directions, so you can type into either field.
One kilopascal equals one kilonewton per square meter, which is why imposed floor loads and wind pressures are stated in kPa or kN/m².
One megapascal equals one newton per square millimeter, which matches the millimeter cross-sections used in structural design, so C30/37 or S355 read directly as stress limits.
