Convert torr to ton-force (short)/sq. inch
Please provide values below to convert torr [Torr] to ton-force (short)/sq. inch [tonf (US)/in^2], or Convert ton-force (short)/sq. inch to torr.
How to Convert Torr to Ton-Force (Short)/sq. Inch
1 Torr = 9.66838732201331e-06 tonf (US)/in^2
Example: convert 15 Torr to tonf (US)/in^2:
15 Torr = 15 × 9.66838732201331e-06 tonf (US)/in^2 = 0.0001450258098302 tonf (US)/in^2

Torr
The torr is a unit of pressure defined as 1 millimeter of mercury (mmHg) at standard gravity and temperature, approximately equal to 133.322 pascals.
History/Origin
The torr was introduced by Evangelista Torricelli in 1644, based on his experiments with mercury barometers, as a unit to measure atmospheric pressure. It was historically used in meteorology and physics before the adoption of the pascal.
Current Use
Today, the torr is primarily used in fields like vacuum technology, physics, and medicine (e.g., blood pressure measurements), although it has largely been replaced by the pascal in most scientific contexts.
Ton-Force (Short)/sq. Inch
Ton-force per square inch (tonf/in^2) 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 per square inch originated from the use of the ton-force as a unit of force in the Imperial system, primarily for measuring pressure in engineering and industrial contexts. It has been used historically in fields such as material testing and hydraulic systems.
Current Use
Today, ton-force per square inch is rarely used in modern engineering, having been largely replaced by the more standard unit of pressure, the pound per square inch (psi). It may still appear in legacy documents or specific industrial applications where imperial units are preferred.
