Please provide values below to convert millimeter mercury (0°C) [mmHg] to ton-force (long)/square foot [tonf (UK)/ft^2], or Convert ton-force (long)/square foot to millimeter mercury (0°C).
How to Convert Millimeter Mercury (0°c) to Ton-Force (Long)/square Foot
1 mmHg = 0.00124307854728091 tonf (UK)/ft^2
Example: convert 15 mmHg to tonf (UK)/ft^2:
15 mmHg = 15 × 0.00124307854728091 tonf (UK)/ft^2 = 0.0186461782092137 tonf (UK)/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 (Long)/square Foot
Ton-force (long) per square foot is a unit of pressure representing the force exerted by one long ton (2,240 pounds) distributed over one square foot.
History/Origin
This unit originated in the UK as a practical measure for engineering and industrial applications, combining the long ton (used primarily in the UK) with square foot to measure pressure in contexts such as structural and mechanical engineering.
Current Use
Today, ton-force per square foot is rarely used in modern engineering, having been largely replaced by SI units like pascals. It may still appear in historical data, specialized fields, or regional contexts within the UK.
