What is a microbar (µbar)?

A microbar is a unit of pressure equal to one millionth of a bar, used to express very small pressures like those in vacuum and atmospheric measurements.

What does kilogram-force per square meter measure?

Kilogram-force per square meter measures pressure as the force exerted by one kilogram-force over one square meter.

Why convert from microbar to kilogram-force per square meter?

Conversion helps reconcile very low pressure measurements from sensitive instruments with legacy engineering data expressed in gravitational metric units.
