Conversion Formula

The formula to convert bar to psi is: pressure in psi = pressure in bar * 14.5038. This works because 1 bar equals 14.5038 pounds per square inch, a standard conversion factor based on the relationship between the metric and imperial pressure units. For example, converting 2 bar: 2 * 14.5038 = 29.0076 psi.

Conversion Example

• Convert 1 bar to psi:
  • Multiply 1 by 14.5038
  • 1 * 14.5038 = 14.5038 psi
• Convert 5 bar to psi:
  • Multiply 5 by 14.5038
  • 5 * 14.5038 = 72.519 psi
• Convert 10 bar to psi:
  • Multiply 10 by 14.5038
  • 10 * 14.5038 = 145.038 psi
• Convert 0.5 bar to psi:
  • Multiply 0.5 by 14.5038
  • 0.5 * 14.5038 = 7.2519 psi

Conversion Definitions

Bar

A bar is a metric unit of pressure equal to 100,000 pascals, roughly the atmospheric pressure at sea level. Used mainly in Europe and in scientific contexts, it measures force applied over an area, often in weather reports and industrial systems.

Psi

Pounds per square inch (psi) is an imperial pressure unit measuring force in pounds applied over one square inch. Commonly used in the United States for measuring tire pressures, hydraulics, and other pressure-related applications.
