Please provide values below to convert millimeter mercury (0°C) [mmHg] to ton-force (long)/square inch [tonf (UK)/in^2], or Convert ton-force (long)/square inch to millimeter mercury (0°C).
How to Convert Millimeter Mercury (0°c) to Ton-Force (Long)/square Inch
1 mmHg = 8.63248990854292e-06 tonf (UK)/in^2
Example: convert 15 mmHg to tonf (UK)/in^2:
15 mmHg = 15 × 8.63248990854292e-06 tonf (UK)/in^2 = 0.000129487348628144 tonf (UK)/in^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 Inch
Ton-force per square inch (tonf/in²) 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 (long) originated from the imperial system of units used in the UK, where it was defined as the force exerted by a long ton (2,240 pounds) under standard gravity. It has been used historically in engineering and pressure measurements but has largely been replaced by SI units.
Current Use
Today, ton-force per square inch is rarely used in modern engineering, having been largely replaced by pascals (Pa) or pounds per square inch (psi). It may still appear in legacy systems or specific industrial contexts in the UK.
