What is a torr? The torr is a unit of pressure named after Italian physicist Evangelista Torricelli, equal to 1/760 of a standard atmosphere or approximately 133.322 pascals. The torr definition was originally based on the pressure exerted by a column of mercury one millimeter high, making it closely related to millimeters of mercury (mmHg). The torr is commonly used in vacuum technology, chemistry, and medicine.

Converting torr to other pressure units is essential for vacuum technology, chemistry, and medical applications. One torr equals approximately 133.322 pascals, 0.133322 kilopascals, 0.00133322 bars, approximately 0.0193368 pounds per square inch (psi), 0.00131579 atmospheres, or 1 millimeter of mercury. Torr conversions are fundamental to pressure measurements in vacuum and medical applications, whether you're using a torr converter tool, learning how to convert torr, or performing torr to other units calculations. The torr's relationship to mercury column measurements makes it practical for many scientific and medical applications.

The torr is extensively used in vacuum technology, chemistry, and medicine. A torr converter is valuable for pressure calculations, vacuum technology, and medical applications. Vacuum systems measure pressures in torr. Chemists use torr for pressure measurements in reactions and experiments. Medical professionals measure blood pressure and other physiological pressures in torr or millimeters of mercury. The torr's relationship to mercury column measurements makes it essential for many scientific and medical applications, making torr converter tools valuable resources for professionals in vacuum technology, chemistry, and medicine.

What is PSI? PSI (pounds per square inch) is a unit of pressure in the British imperial and US customary systems, representing the pressure resulting from a force of one pound-force applied to an area of one square inch. The PSI definition makes it widely used in the United States and United Kingdom for measuring pressures in engineering, automotive, and industrial applications. One PSI equals approximately 6,894.76 pascals or 0.0689476 bars.

Converting PSI to other pressure units is essential for engineering, automotive, and industrial applications, especially for international communication. One PSI equals approximately 6,894.76 pascals, 6.89476 kilopascals, 0.0689476 bars, 0.068046 atmospheres, or 51.7149 torr. PSI conversions are fundamental to pressure measurements in countries using imperial units, whether you're using a PSI converter tool, learning how to convert PSI, or performing PSI to other units calculations. The PSI's practical scale makes it ideal for everyday pressure measurements in countries using imperial systems.

PSI is extensively used in the United States and United Kingdom for automotive, engineering, and industrial applications. A PSI converter is valuable for pressure calculations, engineering design, and automotive applications. Tire pressures are measured in PSI. Hydraulic systems and pneumatic systems use PSI for pressure specifications. Industrial equipment measures operating pressures in PSI. While most of the world uses metric pressure units, PSI remains deeply embedded in American and British engineering and automotive industries, making PSI converter tools valuable resources for professionals and consumers.
