Torr (Torr) to Millibar (mbar) 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.
Millibar
The millibar (mbar) is a unit of pressure equal to one thousandth of a bar (100 Pa). It is the standard unit for atmospheric pressure in meteorology: standard atmospheric pressure is 1,013.25 mbar, and weather maps plot isobars (lines of equal pressure) in millibars or hectopascals (1 hPa = 1 mbar). The eye of a powerful hurricane can have a central pressure below 900 mbar, while high-pressure systems typically exceed 1,020 mbar.
