Centimeter Water (4°c)
Centimeter water (4°C), symbol cmH2O, is a unit of pressure representing the pressure exerted by a one-centimeter column of water at 4 degrees Celsius.
History/Origin
The centimeter water was developed as a practical unit of pressure measurement in medical and engineering contexts, especially for low-pressure measurements such as respiratory and fluid pressure, originating from the use of water columns in manometers.
Current Use
It is primarily used in medical settings to measure intracranial pressure, respiratory pressures, and other low-pressure applications where precise measurement of small pressure differences is required.
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.
