How it works

The converter applies a single fixed factor:

psi = bar × 14.50377378

This comes from the SI definitions: 1 bar = 100,000 pascals and 1 psi = 6894.757293 pascals, so dividing gives 14.50377378. To go the other way, the tool inverts the formula (bar = psi ÷ 14.50377378), which is why typing into the PSI field fills in the bar value automatically.

Example

Convert 3 bar to psi:

3 × 14.50377378 = 43.5113 psi

And 35 psi back to bar:

35 ÷ 14.50377378 = 2.4132 bar
