Pounds per Square Inch to Pascals Converter

To convert a measurement in pounds per square inch to pascals, multiply the value by 6,894.7573. The conversion factor comes from the relationship between both units and the pascal.

For example, to convert 5 psi to pascals: 5 × 6,894.7573 = 34,473.7865 Pa.

Pounds per square inch (psi) is an imperial unit of pressure equal to the force of one pound-force applied to an area of one square inch, or about 6,894.76 pascals. Rooted in the imperial system, psi remains the dominant pressure unit in the United States. It appears on tire gauges, air compressors, and hydraulic equipment throughout North America.

Common uses of pounds per square inch include: Tire pressure in the United States; Air compressors and pneumatic tools; Hydraulic system ratings; Plumbing and water pressure specifications.

A pascal is the SI derived unit of pressure, equal to one newton of force per square meter (1 N/m²). Named after the French mathematician and physicist Blaise Pascal, the unit was adopted by the International System of Units in 1971. It is a small unit, so everyday pressures are usually expressed in kilopascals or bars.

Common uses of pascals include: Scientific and engineering stress calculations; Meteorological reporting (via hectopascals); Material strength and tensile testing; Fluid mechanics and aerodynamics.

Here are some common values converted:

1 psi = 6,894.7573 Pa 5 psi = 34,473.7865 Pa 10 psi = 68,947.5729 Pa 50 psi = 344,737.8647 Pa 100 psi = 689,475.7293 Pa
