The PSI to Bar Conversion Calculator is a simple, yet powerful online tool for converting pressure measurements between PSI (pounds per square inch) and bar. It is ideal for professionals in engineering, meteorology, and other fields where precise pressure measurements are required.

PSI to Bar Converter

Convert pressure between PSI and bar.

How to Use

Enter a value in the PSI field to convert it to bar, or input a value in the bar field to get the equivalent in PSI. The calculator supports bidirectional conversions, automatically updating the corresponding value as you type.

Conversion Formula

The calculator uses these formulas:

  • To convert PSI to bar: Bar = PSI / 14.5038
  • To convert bar to PSI: PSI = Bar * 14.5038

These formulas ensure accurate conversions based on the standard relationship between PSI and bar.

Educational Insight

PSI, or pounds per square inch, is a unit of pressure commonly used in the United States and other countries still using the imperial system. It measures the pressure exerted by a pound-force applied to an area of one square inch. On the other hand, the bar is a metric unit of pressure, not officially a part of the International System of Units (SI) but commonly used in various scientific contexts.

The bar is roughly equivalent to atmospheric pressure at sea level. This calculator provides a convenient way to convert between these two widely used pressure units, bridging the gap between different measurement systems.
