Convert Inches of Water to Millimeters of Mercury - inH2O to mmHg. Inch of water (inH2O) Price of commodities: gold, silver, oil, live cattles and more. This is a useful unit of measurement as it represents the percentage of vacuum and is widely used when discussing a general vacuum system. However, the torr measurement scale is more accurate as it has with a datum point of zero atmospheric pressure. This article is intended as a general guide and as with any industrial application involving machinery choice, independent professional advice should be sought to ensure correct selection and installation. This site is my passion, and I regularly adding new tools/apps. This conversion is simple using 50%, but if the torr reading were 200, then the equivalent in “Hg would be 21.75. For more accurate vacuum applications where the user must have a known vacuum level, an absolute vacuum unit should be used. mm of mercury to inches of water, or enter any two units below: inches of water to inch of mercury Metric Pound per square inch (psi) Thank you. inches of water to kilopond/square meter A system running at 50% vacuum is either 380 Torr or 15″Hg.
