Bar (bar) to Torr (Torr) Conversion
Bar
The bar is a unit of pressure equal to exactly 100,000 pascals (100 kPa), accepted for use with the SI by the BIPM. It is close to one standard atmosphere (1 atm = 1.01325 bar) making it convenient for many practical applications. The bar is widely used in meteorology (weather maps), industrial gas and fluid systems, and tyre inflation in continental Europe. A typical car tyre is inflated to 2.2–2.5 bar; scuba diving tanks are filled to 200–300 bar.
Torr
The torr is a unit of pressure named after Evangelista Torricelli, the Italian physicist who invented the mercury barometer in 1643. One torr is defined as exactly 1/760 of a standard atmosphere (approximately 133.322 Pa). Numerically nearly identical to the millimetre of mercury (mmHg), it differs by less than 0.000015%. The torr is used in vacuum science and engineering: rough vacuum is 1–100 torr, fine vacuum 10⁻³–1 torr, and ultra-high vacuum below 10⁻⁹ torr.
