Convert centimeter water (4°C) to ton-force (long)/square inch
Please provide values below to convert centimeter water (4°C) [cmH2O] to ton-force (long)/square inch [tonf (UK)/in^2], or Convert ton-force (long)/square inch to centimeter water (4°C).
1 cmH2O = 6.3495320099e-06 tonf (UK)/in^2. To convert centimeter water (4°C) to ton-force (long)/square inch, multiply the value by 6.3495320099e-06; to go the other way, divide by it (1 tonf (UK)/in^2 = 157491.921994 cmH2O). Both units measure pressure and appear in everyday as well as technical calculations, so switching between them quickly is often useful.

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 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 It has been used historically in engineering and pressure measurements but has largely been replaced by SI units.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.
