Convert Torr to Barye (torr to Ba)

Torr (torr) and Barye (Ba) are both units of pressure. With the conversion form below, you can effortlessly and accurately convert torr to barye. This free online calculator tool makes it simple and easy to perform the conversion from torr unit to the Ba unit.

Pressure is the force applied perpendicular to a surface per unit area: P = F / A. The SI unit is the pascal (Pa), equal to one newton per square metre (1 Pa = 1 N/m²). Practical applications use larger units: the bar (1 bar = 100,000 Pa, close to standard atmospheric pressure), atmosphere (atm) (1 atm = 101,325 Pa), and psi (pounds per square inch, used in the US for tire and gas pressures). Blood pressure is measured in mmHg (millimetres of mercury), also called torr.

Torr (symbol: Torr) is a unit of pressure defined as exactly 133.322368421 pascals, equivalent to one millimeter of mercury (mmHg) under standard conditions. The torr is widely used in vacuum technology, physics, analytical chemistry, and medical applications to measure low-pressure environments. It is commonly used to specify vacuum pump performance, laboratory vacuum systems, and pressure in scientific instruments. Torr is frequently converted to pascals, millimeters of mercury (mmHg), and standard atmospheres (atm) for engineering, laboratory, and industrial pressure measurements.

The barye (symbol: Ba) is a CGS unit of pressure equal to one dyne per square centimeter or exactly 0.1 pascal. It was widely used in the centimetre-gram-second (CGS) system before the widespread adoption of SI units. Today, the barye is mainly encountered in historical scientific literature and older engineering references. It is part of the CGS system of units.

One barye is equal to 0.1 pascal, 1 dyne per square centimeter, 0.000001 bar, 0.0001 kilopascal, and 9.86923×10^-7 standard atmosphere. Although obsolete in most applications, the barye remains an important historical pressure unit.
