How to Convert Torr to Newton/square Meter
1 Torr = 133.322368 N/m^2
Example: convert 15 Torr to N/m^2:
15 Torr = 15 × 133.322368 N/m^2 = 1999.83552 N/m^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in fields like vacuum technology, physics, and medicine (e.g., blood pressure measurements), although it has largely been replaced by the pascal in most scientific contexts.
Newton/square Meter
The newton per square meter (N/m²) is the SI derived unit of pressure, representing the force of one newton applied over an area of one square meter.
History/Origin
The unit was established as part of the International System of Units (SI) in 1960, replacing earlier units like the pascal, which is now the standard SI unit for pressure.
Current Use
N/m², or pascals (Pa), is widely used in science, engineering, and meteorology to measure pressure, stress, and related quantities.
