Convert pound force per square inch to pascal
Pound-Force per Square Inch
Pound-force per square inch (lbf/in²), universally known as psi, is a unit of pressure equal to approximately 6,894.76 pascals. It is one of the most widely used pressure units in the United States, applied in tyre inflation, hydraulics, pneumatics, and boiler ratings. One psi equals 144 psf and approximately 0.0689 bar.
Pascal
The pascal (Pa) is the SI derived unit of pressure, defined as one newton per square metre (N/m²). It was adopted by the General Conference on Weights and Measures in 1971 and named after the French mathematician and physicist Blaise Pascal. Standard atmospheric pressure is approximately 101,325 Pa, and it is widely used in science, engineering, and meteorology.
