It is defined as the pressure exerted by a column of mercury of 1 inch in height at 32 °F 0 °C at the standard acceleration of gravity. 1 inHg = 3,386.389 pascals at 0 °C.
By contrast, psia measures pressure relative to a vacuum such as that in space. At sea level, Earth's atmosphere actually exerts a pressure of 14.7 psi. Humans do not feel this pressure because internal pressure of liquid in their bodies matches the external pressure. If a pressure gauge is calibrated to read zero in space, then at sea level on Earth it would read 14.7 psi. Thus a reading of 30 psig on a tire.
1 inHg = 3,386.389 pascals at 0 °C. Aircraft operating at higher altitudes above 18,000 feet set their barometric altimeters to a standard pressure of 29.92 inHg or 1,013.2 hPa 1 hPa = 1 mbar regardless of the actual sea level pressure, with inches of mercury used in the U.S. and Canada. The resulting altimeter readings are known as flight. Pressure unit conversion between psi and inch mercury 32 F, inch mercury 32 F to psi conversion in batch, psi inHg conversion chart.
Using a density of 13,595.1 kg/m³ at 0 degC and standard gravity of 9.80665 m/s² to calculate what 1 inHg would generate in pascals SI unit, a pounds/sq inch reading can be converted to an equivalent pressure in inches of mercury using the following calculation: 1 inHg = 3386.39 pascals Pa 1 psi = 6,894.76 pascals Pa.
14.7psia = about 30inhg. thus, let 14.7 be 15 for easier calculations. if 15 psia = 30 inhg then. 1 psia = 30/15 inhg. therefore 1 psia = 2 inhg. or 1 inhg = 0.5 psia.
Pressure unit conversion between newton/square meter and inch mercury 32 F, inch mercury 32 F to newton/square meter conversion in batch, N/m2 inHg conversion chart.
2.03602 Inch Mercury 32°F inHg Psi: Psi is the abbreviation of pound per square inch, and is widely used in British and American. 1 psi = 6,894.76 Pascals. Inch Mercury 32°F: Inch of mercury abbreviated: inHg is a British and American unit of measurement for pressure.
The above form works if you are measuring differential pressure, such as the difference in psi between two points. It also gives the correct answer for absolute pressure, assuming you are measuring psia, which is the pressure relative to absolute zero vacuum. Inch Mercury 32°F: Inch of mercury abbreviated: inHg is a British and American unit of measurement for pressure. It is defined as the pressure exerted by a column of mercury of 1 inch in height at 32 °F 0 °C at the standard acceleration of gravity. Inch of mercury is still widely used in American. 1 inHg = 3,386.389 pascals at 0 °C.
PSIA =.491130 x inHg. Atmospheric pressure at sea level is 14.7 pounds per square inch. Psia pounds per square inch absolute is also 14.7 pounds per square inch.
PSIA – PSI Absolute Absolute pressure is measured relative to a full vacuum. The pressure of a vessel completely void of any air molecules would be 0 PSIA, while average atmospheric surface pressure at sea level is roughly 14.7 PSIA. Look up a barometric conversion value for millibar mbar, mb, hectopascal hPa, pounds per square inch psi, inches of mercury inHg, millimetres of mercury mmHg or Torr pressure units.

This on the web one-way conversion tool converts pressure or stress units from inches of mercury inHg into pounds per sq. inch psi instantly online. 1 inch of mercury inHg = 0.49 pounds per sq. inch psi. How many pounds per sq. inch psi are in 1 inch of mercury 1 inHg ? How much of pressure or stress from inches of. Yes, this is a vacuum gage. It measures how much the pressure is lower than atmospheric pressure. This gage displays two different units of pressure: kPa kilopascals and “inches of mercury” that’s what the “In Hg” means. The “In” is an abbrevi.
