What is a hectopascal?

A hectopascal (hPa) is a metric pressure unit equal to 100 pascals and is commonly used in meteorology to express air pressure.

What does pound-force per square inch represent?

Pound-force per square inch (psi) is an imperial pressure unit indicating one pound of force applied over an area of one square inch.

Why convert from hectopascal to psi?

This conversion helps translate scientific or meteorological pressure data into engineering and industrial contexts where imperial units are standard.
