Understanding Torr

The torr (symbol: Torr) is a unit of pressure named after Italian physicist Evangelista Torricelli. One torr is equal to 1/760 of a standard atmosphere, making it approximately equal to 1 mmHg (millimeter of mercury).

Common Uses

  • Vacuum technology and measurements
  • Scientific research and laboratory work
  • Medical and respiratory equipment
  • Industrial processes requiring precise pressure control

Conversion Facts
