About Pound/sq inch
Pounds per square inch (psi) is an imperial unit of pressure widely used in the US for tire pressure, hydraulics, and engineering.
Common uses: tire pressure (US), hydraulics, HVAC.
About cmHg (0°C)
The cmhg (0°c) (cmHg) is a unit of pressure and stress. One cmhg (0°c) equals 1333.223874 pascals. UnitConvertLab converts it against every other pressure unit using this exact definition, so results are reproducible to full double precision rather than rounded lookup tables.
Common uses: pressure calculations, engineering and science, education.
