Inch Mercury (60°f)
Inch of mercury (60°F) is a unit of pressure measurement representing the height of a column of mercury 1 inch high at 60°F under standard gravity.
History/Origin
Originally used in barometry and meteorology, the inch of mercury has been a standard unit for measuring atmospheric pressure in the Imperial system since the 19th century.
Current Use
It is still used in some regions, such as the United States, primarily for measuring atmospheric pressure in weather reports and aviation, although it is gradually being replaced by Pascals in scientific contexts.
Ton-Force (Long)/square Inch
Ton-force per square inch (tonf/in²) is a unit of pressure representing the force exerted by one ton-force distributed over an area of one square inch.
History/Origin
The ton-force (long) originated from the imperial system of units used in the UK, where it was defined as the force exerted by a long ton (2,240 pounds) under standard gravity. It has been used historically in engineering and pressure measurements but has largely been replaced by SI units.
Current Use
Today, ton-force per square inch is rarely used in modern engineering, having been largely replaced by pascals (Pa) or pounds per square inch (psi). It may still appear in legacy systems or specific industrial contexts in the UK.
