About Torr
The torr is defined as exactly 1/760 of a standard atmosphere ≈ 133.322 Pa - effectively replacing mmHg with an exact definition. Named after Evangelista Torricelli (1608-1647), inventor of the barometer. Vacuum science universally uses torr: rough vacuum 760-1 torr; medium vacuum 1-10⁻³ torr; high vacuum 10⁻³-10⁻⁷ torr; ultra-high vacuum below 10⁻⁹ torr. UHV systems for surface science, particle accelerator beam tubes, and space simulation chambers reach 10⁻¹¹-10⁻¹² torr. 1 torr = 133.322 Pa.
About Pascals
The pascal (Pa) is the SI unit of pressure - 1 N/m², named after Blaise Pascal (1623-1662). Standard sea-level atmosphere ≈ 101,325 Pa. One pascal is very small: roughly the pressure of a single banknote lying flat. Pascal is simultaneously the SI unit for mechanical stress and elastic modulus: structural steel Young's modulus ~200 GPa; rubber shear modulus ~0.5 MPa. Used universally in fluid mechanics, acoustics, atmospheric science, and materials engineering. 1 Pa = 1 N/m².
