Convert centimeter mercury (0°C) to ton-force (short)/sq. inch
Please provide values below to convert centimeter mercury (0°C) [cmHg] to ton-force (short)/sq. inch [tonf (US)/in^2], or Convert ton-force (short)/sq. inch to centimeter mercury (0°C).
How to Convert Centimeter Mercury (0°c) to Ton-Force (Short)/sq. Inch
1 cmHg = 9.66838869987182e-05 tonf (US)/in^2
Example: convert 15 cmHg to tonf (US)/in^2:
15 cmHg = 15 × 9.66838869987182e-05 tonf (US)/in^2 = 0.00145025830498077 tonf (US)/in^2

Centimeter Mercury (0°c)
Centimeter mercury (0°C) is a unit of pressure measurement representing the pressure exerted by a one-centimeter column of mercury at 0°C.
History/Origin
The centimeter mercury was historically used in barometry and pressure measurements before the adoption of the pascal. It originated from the use of mercury columns in barometers to measure atmospheric pressure, with the unit reflecting the height of the mercury column.
Current Use
Today, the centimeter mercury is largely obsolete and replaced by SI units like the pascal. However, it is still used in some medical and historical contexts to measure blood pressure and atmospheric pressure in certain regions.
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.
