Convert psi to pa

Pound per square inch

Pound per square inch is a pressure unit based on one pound-force applied over one square inch.

Psi became common in US customary pressure measurement and remains widely used on gauges and equipment labels.

psi is used for tires, compressors, hydraulics, pneumatics, pressure gauges, industrial equipment, and service documentation.

Pascal

A pascal is the SI pressure unit equal to one newton per square meter.

The pascal became the standard SI pressure unit for scientific, engineering, and technical measurement.

Pa is used in sensors, formulas, simulations, laboratory data, fluid mechanics, acoustics, ventilation, and material testing.

How to Convert Pound per square inch to Pascal

Mathematically, pascal (Pa) = pound per square inch (psi) converted with the formula below.

1 psi = 6,894.757293 Pa

1 Pa = 0.000145 psi

Formula: value × 6894.75729317

Example: 15 psi = 103,421.359398 Pa

1. Start with the pressure value in psi.
2. Use 6894.757293168 Pa for each psi.
3. Multiply the psi value by 6894.757293168.
4. Use Pa as the converted result.

Precision note: Use exactly 6894.757293168 Pa per psi. Preserve source precision before multiplying, especially for equipment ratings.
