Please provide values below to convert inch water (4°C) [inAq] to ton-force (long)/square inch [tonf (UK)/in^2], or Convert ton-force (long)/square inch to inch water (4°C).
How to Convert Inch Water (4°c) to Ton-Force (Long)/square Inch
1 inAq = 1.61278079382099e-05 tonf (UK)/in^2
Example: convert 15 inAq to tonf (UK)/in^2:
15 inAq = 15 × 1.61278079382099e-05 tonf (UK)/in^2 = 0.000241917119073148 tonf (UK)/in^2

Inch Water (4°c)
Inch water (4°C) is a unit of pressure measurement representing the pressure exerted by a one-inch column of water at 4 degrees Celsius.
History/Origin
The inch water (4°C) has been used historically in engineering and meteorology to measure low-pressure differences, especially in ventilation and HVAC systems, as a practical alternative to more complex units.
Current Use
Today, inch water (4°C) is primarily used in the United States for measuring low-pressure differences in HVAC, ventilation, and fluid systems, serving as a standard unit in these fields within the pressure converter category of common converters.
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 It has been used historically in engineering and pressure measurements but has largely been replaced by SI units.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.
