Convert torr to ton-force (long)/square foot
Please provide values below to convert torr [Torr] to ton-force (long)/square foot [tonf (UK)/ft^2], or Convert ton-force (long)/square foot to torr.
How to Convert Torr to Ton-Force (Long)/square Foot
1 Torr = 0.00124307837012768 tonf (UK)/ft^2
Example: convert 15 Torr to tonf (UK)/ft^2:
15 Torr = 15 × 0.00124307837012768 tonf (UK)/ft^2 = 0.0186461755519152 tonf (UK)/ft^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in fields like vacuum technology, physics, and medicine (e.g., blood pressure measurements), although it has largely been replaced by the pascal in most scientific contexts.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 (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.
