What is Pound per square inch?

The pound per square inch is a unit of pressure expressing force in pounds-force applied to an area of one square inch. It is widely used in the United States and United Kingdom. Car tire pressure in the US is typically 30 to 35 psi, and industrial compressed air systems commonly operate at 90 to 150 psi. Fire sprinkler systems, natural gas pipelines, and hydraulic tools all use psi ratings. One psi equals approximately 6,895 pascals.

What is Hectopascal?

The hectopascal equals 100 pascals and is the standard unit for atmospheric pressure in meteorology worldwide. Standard atmospheric pressure is 1013.25 hPa, and weather reports use hectopascals when describing high and low pressure systems and typhoon central pressures (such as 950 hPa). One hectopascal is exactly equal to one millibar. The international meteorological community switched from millibars to hectopascals in 1992.
