Inch Mercury (32°f)
Inch of mercury at 32°F (inHg) is a unit of pressure measurement representing the height of a mercury column in inches, used primarily in meteorology and aviation.
History/Origin
The inch of mercury originated from barometric pressure measurements using a mercury barometer, with its use dating back to the 18th century. It became a standard unit in weather reporting and altitude measurement.
Current Use
Today, inHg is primarily used in meteorology to report atmospheric pressure, especially in the United States, and in aviation for altitude and pressure readings.
Ton-Force (Long)/square Foot
Ton-force (long) per square foot is a unit of pressure representing the force exerted by one long ton (2,240 pounds) distributed over one square foot.
History/Origin
This unit originated in the UK as a practical measure for engineering and industrial applications, combining the long ton (used primarily in the UK) with square foot to measure pressure in contexts such as structural and mechanical engineering.
Current Use
Today, ton-force per square foot is rarely used in modern engineering, having been largely replaced by SI units like pascals. It may still appear in historical data, specialized fields, or regional contexts within the UK.
