There is often much confusion with regards to the units used to measure the level of vacuum being generated in an industrial application. In North America, “torr” [a unit of measurement devised by Italian scientist Evangelista Torricelli (b.1608)] is very popular. Convert to pascals, bars, and inches of mercury. Metre of water (mH2O) inches of water to sthene/square meter A system running at 50% vacuum is either 380 Torr or 15″Hg. Millimeters of mercury. Any feedback is appreciated. symbols, abbreviations, or full names for units of length, I've spent over 10 trillion microseconds (and counting), on this project. Inch of water (inH2O) Use this page to learn how to convert between inches of water and millimeters of mercury.
