Convert millimeter water (4°C) to ton-force (short)/sq. inch
Please provide values below to convert millimeter water (4°C) [mmH2O] to ton-force (short)/sq. inch [tonf (US)/in^2], or Convert ton-force (short)/sq. inch to millimeter water (4°C).
How to Convert Millimeter Water (4°c) to Ton-Force (Short)/sq. Inch
1 mmH2O = 7.1114758527875e-07 tonf (US)/in^2
Example: convert 15 mmH2O to tonf (US)/in^2:
15 mmH2O = 15 × 7.1114758527875e-07 tonf (US)/in^2 = 1.06672137791813e-05 tonf (US)/in^2

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.
Ton-Force (Short)/sq. Inch
Ton-force per square inch (tonf/in^2) 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 per square inch originated from the use of the ton-force as a unit of force in the Imperial system, primarily for measuring pressure in engineering and industrial contexts. It has been used historically in fields such as material testing and hydraulic systems.
Current Use
Today, ton-force per square inch is rarely used in modern engineering, having been largely replaced by the more standard unit of pressure, the pound per square inch (psi). It may still appear in legacy documents or specific industrial applications where imperial units are preferred.
