How to use it
- Type the value in the psi box.
- Read the result in pascals as you type, and pick the precision you need.
- Swap the direction to convert back, or copy the result.
How it is calculated
Pa = psi × 6,894.757293
Multiply the value in psi by 6,894.757293 to get pascals.
Example
To convert 25 psi to pascals: 25 × 6,894.757293 = 172,369 Pa.

About the units
- Psi
- One pound-force per square inch, about 6894.757 pascals from the exact definitions of the pound, inch and standard gravity.
- Pascal
- The SI unit of pressure, equal to a force of one newton acting on one square meter.
Limits and caveats
- Results are rounded for display and computed with the browser's floating point precision (about 15 significant digits).
- Both unit factors are exact by their official definitions.
Questions about this tool
How many pascals are in one psi?
1 psi = 6,894.76 Pa exactly.
How do I convert psi to pascals?
Use Pa = psi × 6,894.757293. For example, 25 psi = 172,369 Pa.
How many psi are in one pascal?
1 Pa = 0.000145038 psi.
What is the difference between gauge and absolute pressure?
Gauge pressure is measured from the surrounding air pressure, while absolute pressure starts from a perfect vacuum. These converters change the unit only, so a gauge reading stays a gauge reading.
Are torr and mmHg the same?
Almost. One torr is 101325/760 Pa, about 133.322368 Pa, and one conventional mmHg is 133.322387 Pa, a difference of less than one part per million. For everyday use you can treat them as equal.
