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in fields like vacuum technology, physics, and medicine (e.g., blood pressure measurements), although it has largely been replaced by the pascal in most scientific contexts.
Gram-Force/sq. Centimeter
Gram-force per square centimeter (gf/cm²) is a unit of pressure representing the force exerted by one gram-force applied over an area of one square centimeter.
History/Origin
The unit originated from the use of gram-force, a non-SI unit of force based on the gram, and was commonly used in engineering and scientific contexts before the adoption of SI units. It was primarily used in regions and industries where the metric system was prevalent.
Current Use
Today, gf/cm² is largely considered obsolete and is rarely used in modern scientific or engineering applications. Pressure measurements are typically expressed in pascals (Pa) or bar, but the unit may still appear in legacy systems or specific niche contexts.
