Understanding the Units

What is a Pounds per Square Inch?

One pound-force per square inch (psi) equals approximately 6,894.757 pascals.

Common contexts: tire pressure, plumbing, pneumatic systems (US).

What is a Pascal?

The pascal is the SI derived unit of pressure, equal to one newton of force per square meter (1 Pa = 1 N/m²).

Named after Blaise Pascal (1623–1662), the French mathematician and physicist whose experiments characterized atmospheric pressure.

Common contexts: fluid mechanics, meteorology.

FAQ

What does PSI stand for?

PSI stands for pounds per square inch. It measures the pressure exerted by one pound-force applied to an area of one square inch and is widely used in the United States and United Kingdom.

What is the typical tire pressure in PSI and pascals?

Most passenger car tires are inflated to 32-35 PSI, which equals roughly 220,632 to 241,317 pascals (220-241 kPa). The recommended pressure is usually printed on the tire sidewall or driver door jamb.

How do I convert PSI to kilopascals instead of pascals?

Multiply PSI by 6.89476 to get kilopascals (kPa). Since 1 kPa = 1,000 Pa, this is simply the pascal conversion factor divided by 1,000.

Is PSI used outside the United States?

PSI is primarily used in the US, UK, and countries influenced by their engineering standards. Most of the world uses bar, pascal, or kilopascal for pressure measurement.

How many pascals are in 1 pounds per square inch?

1 psi equals 6894.76 Pa.

How do you convert pounds per square inch to pascals?

Multiply the pounds per square inch value by 6894.76. Formula: Pa = psi × 6894.76.

How many pascals are in 5 pounds per square inch?

5 psi = 34473.8 Pa.

How do you convert pascals back to pounds per square inch?

Use the inverse formula: psi = Pa ÷ 6894.76. For example, 1 Pa = 0.000145 psi.

What is the difference between Pounds per Square Inch and Pascal?

One pound-force per square inch (psi) equals approximately 6,894.757 pascals. The pascal is the SI derived unit of pressure, equal to one newton of force per square meter (1 Pa = 1 N/m²).
