To convert pounds per square inch (psi) to pascals (Pa), use this fixed factor:
Formula (psi to Pa):
Quick examples:
Tip: If you need a clean number, round to the nearest whole pascal.
PSI means pounds per square inch. It measures pressure based on force in pounds spread over one square inch. You’ll see PSI used for tires, air tools, gas systems, and other pressure-rated equipment.
A pascal is the SI unit of pressure. It measures one newton of force over one square meter (1 Pa = 1 N/m²). Pascals are common in science, engineering, weather data, and lab work.
1 PSI equals 6,894.757 Pa.
To convert PSI to pascals, multiply the PSI value by 6,894.757.
Use this formula:
Pa = PSI × 6,894.757
Example:
30 PSI × 6,894.757 = 206,842.71 Pa
Use this formula:
PSI = Pa ÷ 6,894.757
Example:
101,325 Pa ÷ 6,894.757 ≈ 14.6959 PSI
There are 6,894.757 pascals in 1 PSI. For most practical use, people round this to 6,895 Pa.
There are about 0.0001450377 PSI in 1 pascal. Pascals are a small unit, so PSI values often look much smaller than Pa values.
Standard atmospheric pressure is close to 14.6959 PSI, which equals 101,325 Pa. People often round 14.7 PSI to about 101,325 Pa for quick reference.
No. kPa means kilopascals, and 1 kPa = 1,000 Pa.
Since 1 PSI = 6.894757 kPa, you can also convert like this:
kPa = PSI × 6.894757, then multiply by 1,000 to get Pa.
Yes. Bar is another pressure unit used in many countries.
They use different base units and reference areas. PSI uses pounds and square inches. Pascals use newtons and square meters. A square meter is much larger than a square inch, so Pa values usually look bigger.
Rounding depends on your use. For tires and general work, rounding to the nearest 1 Pa or 10 Pa is often fine. For lab or design work, keep more digits or follow your spec sheet.
PSI is often used as gauge pressure (PSIG), which is measured relative to local air pressure. PSIA is absolute pressure, measured relative to a perfect vacuum. The PSI to Pa conversion factor is the same, but you must know whether you’re using gauge or absolute pressure.
No. The conversion is a fixed math relationship between units. Temperature can change the pressure in a system, but it doesn’t change how PSI converts to pascals.
Here are a few quick values (rounded to the nearest pascal):
The Calculate Box tool to convert pounds per square inch to pascals uses the open source script Convert.js to convert units of measurement. To use this tool, simply type a pounds per square inch value in the box and have it instantly converted to pascals.
