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 Pascal?

The pascal is the SI unit of pressure, defined as one newton of force per square meter. Named after French mathematician and physicist Blaise Pascal, it is the foundation for related units like the hectopascal used in weather reports. Since one pascal is a very small amount of pressure, practical applications typically use kilopascals (kPa) or megapascals (MPa). In materials engineering, stress and tensile strength are expressed in megapascals or gigapascals.
