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 a pascal? The pascal (Pa) is the base unit of pressure in the International System of Units (SI), named after French mathematician and physicist Blaise Pascal. The pascal definition identifies one pascal as one newton per square meter, representing the pressure exerted by a force of one newton applied uniformly over an area of one square meter. The pascal is widely used in science, engineering, and meteorology for measuring pressure in various applications.

Converting pascals to other pressure units is essential for understanding pressure measurements across different systems and applications. One pascal equals 0.001 kilopascals, 0.00001 bars, approximately 0.000145038 pounds per square inch (psi), 0.00000986923 atmospheres, or 0.00750062 torr. Pascal conversions are fundamental to pressure measurements, whether you're using a pascal converter tool, learning how to convert pascals, or performing pascal to other units calculations. The pascal's status as the SI unit for pressure makes it essential for scientific calculations and international standards, providing a fundamental unit for measuring force per unit area.

The pascal is extensively used in physics, engineering, meteorology, and scientific research. A pascal converter is valuable for pressure calculations, engineering design, and scientific measurements. Engineers measure fluid pressures, structural loads, and system pressures in pascals. Meteorologists measure atmospheric pressure in pascals or kilopascals. Scientists use pascals for pressure measurements in experiments and calculations. The pascal's status as the SI unit for pressure makes it essential for scientific calculations, making pascal converter tools valuable resources for professionals and researchers.
