About these units
inHg (inches of mercury) and kPa (kilopascals) both measure pressure: force spread over an area.
- inHg — height of a mercury column in inches. Used for weather and aircraft altimeters in the US.
- hPa / mb — hectopascals, identical to millibars. The standard weather unit worldwide.
- mmHg — millimeters of mercury, also called torr. Used for weather in some countries and for blood pressure.
- kPa — kilopascals (10 hPa). Common in Canada and engineering.
- psi — pounds per square inch. Tires, compressors, vacuum gauges.
