Frequently Asked Questions

How do I convert bar to psi?

Multiply bar by 14.5037738 to get psi. Example: 2 bar ≈ 29.0075 psi.

How do I convert psi to bar?

Divide psi by 14.5037738 to get bar. Example: 30 psi ≈ 2.0684 bar.

How accurate is the bar to psi conversion?

Our converter uses the exact conversion factor (1 bar = 14.5037738 psi) as defined by international standards. Results are accurate to 4 decimal places for psi and 6 decimal places for bar.

What is the difference between bar and psi?

Bar is a metric unit (1 bar ≈ atmospheric pressure), while psi (pounds per square inch) is an imperial unit commonly used in the US. Both measure pressure but use different scales.

When should I use bar vs psi?

Use bar for European/metric specifications (automotive, industrial equipment). Use psi for US specifications (tire gauges, HVAC systems, hydraulics in the US market).
