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 Foot
Pound-force per square foot (lbf/ft^2) is a unit of pressure representing the force of one pound-force applied over an area of one square foot.
History/Origin
This unit has been traditionally used in the United States for measuring pressure, especially in fields like construction and engineering, originating from the imperial system of units.
Current Use
Today, pound-force per square foot is primarily used in specific engineering and construction contexts within the US, although it has largely been replaced by SI units like Pascals in scientific and international applications.
