Please provide values below to convert centimeter mercury (0°C) [cmHg] to ton-force (short)/sq. foot [tonf (US)/ft^2], or Convert ton-force (short)/sq. foot to centimeter mercury (0°C).
How to Convert Centimeter Mercury (0°c) to Ton-Force (Short)/sq. Foot
1 cmHg = 0.0139224797275731 tonf (US)/ft^2
Example: convert 15 cmHg to tonf (US)/ft^2:
15 cmHg = 15 × 0.0139224797275731 tonf (US)/ft^2 = 0.208837195913597 tonf (US)/ft^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. Foot
Ton-force per square foot (tonf/ft²) is a unit of pressure representing the force exerted by one ton-force distributed over an area of one square foot.
History/Origin
The ton-force per square foot originated from the use of the ton-force as a unit of force in the Imperial system, primarily in engineering and construction contexts, to measure pressure or stress levels. Its usage has declined with the adoption of SI units but remains relevant in specific industries.
Current Use
Today, ton-force per square foot is rarely used in modern engineering, having been largely replaced by SI units such as pascals. It may still be encountered in legacy systems or specific regional applications related to structural and material stress assessments.
