About both units

From

Pascal

The pascal is the SI unit of pressure — one newton per square metre. Named after Blaise Pascal. 1 Pa is a very small pressure; atmospheric pressure is about 101,325 Pa. Pressure readings in engineering are usually in kPa or MPa.

Real-world: Atmospheric pressure: 101,325 Pa. Conversation level: 0.001 Pa sound pressure. Truck tyre: 900,000 Pa.

Pound per Square Inch

psi

Pounds per square inch equals approximately 6895 Pa. It is the dominant pressure unit in the US — tyre pressures, plumbing, compressed air. Standard US tyre pressure: 32–35 psi.

Real-world: US tyre: 32–35 psi. Water supply: 40–60 psi. SCUBA tank: 3000 psi. Car AC system: 30–200 psi.

Tips & common mistakes

Quick tips

1 Pa = 1 N/m².
1 kPa = 1000 Pa; 1 MPa = 1,000,000 Pa; 1 bar = 100,000 Pa.
Use kPa, MPa or bar for practical engineering work.

Avoid these

Confusing Pa with psi — 1 psi = 6895 Pa.
Using Pa for tyre pressures — 220,000 Pa unwieldy; use 2.2 bar.
Mixing Pa absolute and Pa gauge without specification.

Frequently asked questions

How many psi in a pascal?

One pascal equals 0.000145 psi.

How do I convert pascals to psi?

Multiply the pascal value by 0.000145 to get the equivalent in psi.

What is 100 pascals in psi?

100 pascals equals 0.0145 psi.

Is a pascal bigger than a pound per square inch?

No. 1 pascal equals 0.000145 psi, so one pascal is smaller.

How to convert pascals to psi without a calculator?

Multiply by 0 for a quick estimate; use a calculator for precise results.
