Please provide values below to convert millimeter mercury (0°C) [mmHg] to ton-force (short)/sq. foot [tonf (US)/ft^2], or Convert ton-force (short)/sq. foot to millimeter mercury (0°C).
How to Convert Millimeter Mercury (0°c) to Ton-Force (Short)/sq. Foot
1 mmHg = 0.00139224797275731 tonf (US)/ft^2
Example: convert 15 mmHg to tonf (US)/ft^2:
15 mmHg = 15 × 0.00139224797275731 tonf (US)/ft^2 = 0.0208837195913597 tonf (US)/ft^2

Millimeter Mercury (0°c)
Millimeter mercury (0°C), abbreviated as mmHg, is a unit of pressure measurement based on the height of a column of mercury in millimeters at 0°C under standard gravity.
History/Origin
The mmHg originated from the use of mercury barometers in the 17th century to measure atmospheric pressure. It became a standard unit in meteorology and medicine for measuring blood pressure and other pressure-related phenomena.
Current Use
Today, mmHg is primarily used in medicine to measure blood pressure and in meteorology for atmospheric pressure readings. It is also used in various scientific and industrial applications where precise pressure measurements are required.
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.
