Instant, two-way conversion across common engineering units.
1 psi = 6,894.7573 Pa(Pounds per square inch → Pascal)
To convert pounds per square inch to pascals, multiply the value by 6,894.7573. Pressure conversions link structural loading, material strength grades and mechanical system ratings across metric and US practice.
Pounds per square inch (psi) is the pressure unit of US customary engineering.
The pascal (Pa) is the SI derived unit of pressure, equal to one newton per square meter.
1 psi equals 6,894.7573 Pa.
Multiply the value by 6,894.7573. For example, 10 psi equals 68,947.573 Pa.
1 Pa equals 0.00014503774 psi. 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.
