Torr (Torr) to Pascals (Pa) Conversion
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.
Pascals
The pascal (Pa) is the SI derived unit of pressure, defined as one newton per square metre (N/m²), named after French mathematician Blaise Pascal who studied fluid pressure in the 17th century. Standard atmospheric pressure at sea level is 101,325 Pa (101.3 kPa). The pascal is a small unit for everyday use — a gentle breeze exerts approximately 1 Pa of dynamic pressure — so kilopascals (kPa) and megapascals (MPa) are more common in practical engineering contexts.
