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.
Pascal (Pa)
The pascal is the SI unit of pressure, equal to one newton per square meter. It is a small unit, so kilopascals and megapascals are more common in practice.
