A millibar (mbar) is a metric pressure unit equal to 100 pascals, commonly used in meteorology and atmospheric science.

What does pound-force per square inch (psi) measure?

Psi measures pressure as the force of one pound applied over an area of one square inch, widely used in engineering and automotive fields.

Why convert millibars to psi?

Converting millibars to psi allows translating meteorological pressure readings into units used in mechanical and engineering environments.
