Please provide values below to convert centimeter mercury (0°C) [cmHg] to ton-force (long)/square foot [tonf (UK)/ft^2], or Convert ton-force (long)/square foot to centimeter mercury (0°C).
How to Convert Centimeter Mercury (0°c) to Ton-Force (Long)/square Foot
1 cmHg = 0.0124307854728091 tonf (UK)/ft^2
Example: convert 15 cmHg to tonf (UK)/ft^2:
15 cmHg = 15 × 0.0124307854728091 tonf (UK)/ft^2 = 0.186461782092137 tonf (UK)/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 (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.
