Convert inch water (60°F) to ton-force (long)/square inch
Please provide values below to convert inch water (60°F) [inAq] to ton-force (long)/square inch [tonf (UK)/in^2], or Convert ton-force (long)/square inch to inch water (60°F).
How to Convert Inch Water (60°f) to Ton-Force (Long)/square Inch
1 inAq = 1.61121386826191e-05 tonf (UK)/in^2
Example: convert 15 inAq to tonf (UK)/in^2:
15 inAq = 15 × 1.61121386826191e-05 tonf (UK)/in^2 = 0.000241682080239287 tonf (UK)/in^2

Inch Water (60°f)
Inch water (60°F), symbol inAq, is a unit of pressure measuring the height of a water column at 60°F that exerts a pressure equivalent to one inch of water column.
History/Origin
The inch water unit originated in the United States as a practical measurement for low-pressure applications, particularly in HVAC and fluid systems, based on the height of a water column. Its use has been standardized in various industries for measuring small pressure differences.
Current Use
It is currently used in fields such as HVAC, pneumatic systems, and low-pressure fluid measurements to quantify small pressure differences, especially in the United States.
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 It has been used historically in engineering and pressure measurements but has largely been replaced by SI units.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.
