Convert Bar (bar) to Pound per square inch (psi) instantly.
Formula
value × 14.503773773
| Sample | Converted |
|---|---|
| 1 bar | 14.503774 psi |
| 5 bar | 72.518869 psi |
| 10 bar | 145.037738 psi |
| 100 bar | 1,450.377377 psi |
| 1,000 bar | 14,503.773773 psi |
Convert bar to pounds per square inch by multiplying the bar value by about 14.503773773. This is useful when metric equipment pressure needs to be compared with psi gauges, service manuals, or US customary specifications.
Bar and psi are both common field pressure units, but they belong to different unit systems.
This conversion is useful when equipment documentation, gauges, or service procedures mix metric and US customary pressure units.
A pressure of 6 bar is about 87.0226 psi.
Use bar when following metric equipment data and psi when matching US customary gauges or manuals.
For safety-related pressure ratings, avoid rough approximations and use the full conversion factor.
The conversion does not change gauge pressure into absolute pressure or the other way around.
Bar is common in metric pressure equipment, while psi is common in US customary gauges and service documents.
Converting bar to psi lets the same pressure rating be compared across those systems.
This is especially useful for compressors, hydraulics, pneumatics, pumps, and vehicle-related pressure checks.
One bar is about 14.5038 psi.
That makes 3 bar about 43.5113 psi.
Using the precise factor is better than relying on a rough 15 psi estimate when limits matter.
Bar and psi can both describe gauge or absolute pressure.
The unit conversion preserves the source reference.
Check equipment documentation before comparing values from different sources.
Definition: A bar is a pressure unit equal to 100,000 pascals.
History/Origin: Bar became widely used in practical pressure measurement because it is close to atmospheric pressure.
Current use: bar is used in compressors, pumps, hydraulics, process equipment, diving, mechanical service, and pressure gauges.
Definition: Pound per square inch is a pressure unit based on one pound-force applied over one square inch.
History/Origin: Psi became common in US customary pressure measurement and remains widely used on gauges and equipment labels.
Current use: psi is used for tires, compressors, hydraulics, pneumatics, pressure gauges, industrial equipment, and service documentation.

Precision note: Use 1 bar = 14.503773773 psi. Keep precision when values are used for equipment compatibility or safety checks.
One bar is about 14.503773773 psi.
2 bar is about 29.00754755 psi.
Yes. One bar is close to one standard atmosphere, but it is not exactly the same.
