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 bar? The bar is a unit of pressure approximately equal to atmospheric pressure at sea level, defined as exactly 100,000 pascals or 100 kilopascals. The bar definition makes it widely used in meteorology, oceanography, and engineering, particularly in Europe. Although not an official SI unit, the bar is accepted for use with SI units and provides a convenient scale for measuring pressures near atmospheric pressure.

Converting bars to other pressure units is essential for meteorology, engineering, and industrial applications. One bar equals 100,000 pascals, 100 kilopascals, approximately 14.5038 pounds per square inch (psi), 0.986923 atmospheres, or 750.062 torr. Bar conversions are fundamental to pressure measurements, whether you're using a bar converter tool, learning how to convert bars, or performing bar to other units calculations. The bar's relationship to atmospheric pressure makes it intuitive for many applications, providing a convenient unit for pressures near standard atmospheric conditions.

The bar is extensively used in meteorology, oceanography, engineering, and industrial applications. A bar converter is valuable for pressure calculations, engineering design, and weather measurements. Meteorologists measure atmospheric pressure in bars or millibars. Oceanographers measure water pressure in bars. Engineers use bars for system pressures and fluid dynamics. The bar's relationship to atmospheric pressure makes it essential for many applications, making bar converter tools valuable resources for professionals in meteorology, oceanography, and engineering.
