What is Torr?

The torr is a unit of pressure named after Italian physicist Evangelista Torricelli. It is defined as exactly 1/760 of a standard atmosphere, approximately 133.3 pascals. The torr is widely used in vacuum technology, particularly in semiconductor manufacturing, where process chambers operate at pressures from 10 to the minus 3 to 10 to the minus 8 torr. While nearly identical to the millimeter of mercury, the torr is defined independently.

What is Bar?

The bar is a unit of pressure equal to 100,000 pascals, which is very close to standard atmospheric pressure (101,325 Pa). This convenient relationship makes it widely used in industry. Scuba tank pressure is typically around 200 bar, espresso machines extract at about 9 bar, and fire extinguishers are pressurized to several bar. While not an SI unit, the bar is accepted for use with the SI in many countries.
