Atmosphere to Torr Converter

An atmosphere (atm) is a unit of pressure defined as exactly 101,325 pascals, representing the average atmospheric pressure at sea level. It serves as a reference pressure for many scientific and engineering applications.

The atmosphere was originally defined as the pressure exerted by the Earth's atmosphere at sea level. It became a standard reference pressure in chemistry and physics, providing a convenient baseline for pressure measurements and calculations.

Atmospheres are used in chemistry, physics, and engineering as a reference pressure. They're standard for gas law calculations, chemical reaction conditions, and scientific applications where atmospheric pressure serves as a convenient reference.

A torr is a unit of pressure equal to 1/760 of an atmosphere, approximately 133.322 pascals. Named after Evangelista Torricelli, it's commonly used in vacuum technology and low-pressure applications.

The torr was named after Evangelista Torricelli, inventor of the barometer, and became standard in vacuum technology. It provided a convenient unit for low-pressure measurements, particularly in scientific instruments and vacuum systems.

Torr is extensively used in vacuum technology, scientific instruments, and low-pressure applications. It's standard for vacuum pump specifications, mass spectrometry, and scientific equipment operating under reduced pressure conditions.
