Inch of mercury (inHg and ″Hg) is a non-SI unit of measurement for pressure. It is used for barometric pressure in weather reports, refrigeration and aviation in the United States. It is the pressure exerted by a column of mercury 1 inch (25.4 mm) in …

Inches of mercury or inHg is a non-SI unit for pressure. It is still widely used for barometric pressure in weather reports and aviation in the United States, but is considered somewhat outdated elsewhere. 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.

What is high or low barometric pressure? Adjusted to sea level, a pressure reading above 30.2 inHg is considered to be high pressure, and below 29.8 inHg is considered low.

InHg is a measure of pressure. Get more information and details on the 'inHg' measurement unit, including its symbol, category, and common conversions from inHg to other pressure units.

Inch of Mercury is a British and American unit of measure for pressure. 1 inch of mercury at 0 degrees Celsius (32 deg F) equals 3386.39 pascals. An inch of mercury at zero degrees Celsius is defined as the pressure exerted by a column of mercury with a density of 13,595.1 kg/m3 under the pull of gravity at 9.80665 m/s2.

Seamlessly convert between key pressure units, such as Inches of Mercury (inHg), Millimeters of Mercury (mmHg), Pascal (Pa), HectoPascal (hPa) or Millibar (mb), Bar (bar), Atmosphere (atm), and Pound per Square Inch (psi).

2024年11月3日 · Understanding the Units. Before diving into the conversion process, it’s essential to understand the units involved. Inches of mercury (inHg) is a unit of pressure, where the pressure is measured in terms of the height of a column of mercury. On the other hand, pounds per square inch (psi) is a unit of pressure, where the pressure is measured in terms of the …

2025年2月6日 · The inHg is traditionally used in meteorology for measuring atmospheric pressure, while psi is widely used in engineering and technical applications. Understanding inHg and psi. Inches of mercury (inHg) is a manometric unit of pressure formerly defined as the extra pressure generated by a column of mercury one inch high. Given that mercury is ...
