Unit definitions

Inch of mercury (inHg)
An inch of mercury is the pressure exerted by a 1 inch column of mercury, conventionally about 3386.389 pascals. It is used in the United States for barometric pressure in weather reports and aviation.
Kilopascal (kPa)
A kilopascal is 1000 pascals. It is the common SI unit for tire pressures, weather reports and engineering in metric countries.
