What is an atmosphere? The atmosphere (atm) is a unit of pressure approximately equal to the average atmospheric pressure at sea level on Earth, defined as exactly 101,325 pascals. The atmosphere definition makes it a convenient reference for pressure measurements, as it represents a familiar baseline pressure. The standard atmosphere is widely used in science, engineering, and meteorology as a reference pressure.

Converting atmospheres to other pressure units is essential for scientific research, engineering, and understanding pressure relative to standard atmospheric conditions. One atmosphere equals 101,325 pascals, 101.325 kilopascals, 1.01325 bars, approximately 14.6959 pounds per square inch (psi), or 760 torr. Atmosphere conversions are fundamental to pressure measurements, whether you're using an atmosphere converter tool, learning how to convert atmospheres, or performing atmosphere to other units calculations. The atmosphere's relationship to sea-level atmospheric pressure makes it intuitive for many applications, providing a convenient reference point for pressure measurements.

The atmosphere is used in science, engineering, and meteorology as a reference pressure. An atmosphere converter is valuable for pressure calculations, scientific measurements, and engineering applications. Scientists use atmospheres for pressure measurements in experiments and calculations. Engineers reference system pressures to atmospheric pressure. The atmosphere's relationship to sea-level atmospheric pressure makes it essential for many applications, making atmosphere converter tools valuable resources for professionals and researchers.

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.
