Convert ton-force (long)/square inch to millimeter water (4°C)
Please provide values below to convert ton-force (long)/square inch [tonf (UK)/in^2] to millimeter water (4°C) [mmH2O], or Convert millimeter water (4°C) to ton-force (long)/square inch.
1 tonf (UK)/in^2 = 1574919.21994 mmH2O. To convert ton-force (long)/square inch to millimeter water (4°C), multiply the value by 1574919.21994; to go the other way, divide by it (1 mmH2O = 6.3495320099e-07 tonf (UK)/in^2). Both units measure pressure and appear in everyday as well as technical calculations, so switching between them quickly is often useful.

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 It has been used historically in engineering and pressure measurements but has largely been replaced by SI units.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.
Millimeter Water (4°c)
Millimeter water (4°C) is a unit of pressure measuring the height of a water column at 4 degrees Celsius that exerts a specific pressure.
History/Origin
The unit originated from the use of water columns to measure pressure, particularly in hydrology and medical applications, with standardization based on the density of water at 4°C.
Current Use
It is primarily used in medical and scientific contexts to measure low pressures, such as intracranial pressure, respiratory pressures, and in calibration of pressure sensors.
