Centimeter Mercury (0°c)
Centimeter mercury (0°C) is a unit of pressure measurement representing the pressure exerted by a one-centimeter column of mercury at 0°C.
History/Origin
The centimeter mercury was historically used in barometry and pressure measurements before the adoption of the pascal. It originated from the use of mercury columns in barometers to measure atmospheric pressure, with the unit reflecting the height of the mercury column.
Current Use
Today, the centimeter mercury is largely obsolete and replaced by SI units like the pascal. However, it is still used in some medical and historical contexts to measure blood pressure and atmospheric pressure in certain regions.
Pound-Force/square Inch
Pound-force per square inch (lbf/in^2) is a unit of pressure representing the force of one pound-force applied over an area of one square inch.
History/Origin
The unit originated from the Imperial system and became widely used in the United States for measuring pressure, especially in engineering and tire pressure contexts.
Current Use
Today, lbf/in^2, commonly known as psi, is still used in various fields such as automotive, aerospace, and industrial applications to measure pressure.
