Convert Millibar to Torr (mbar to Torr)

Millibar (mbar) and Torr (Torr) are both units of pressure. With the conversion form below, you can effortlessly and accurately convert millibar to torr. This free online calculator tool makes it simple and easy to perform the conversion from mbar unit to the Torr unit.

Pressure is the force applied perpendicular to a surface per unit area: P = F / A. The SI unit is the pascal (Pa), equal to one newton per square metre (1 Pa = 1 N/m²). Practical applications use larger units: the bar (1 bar = 100,000 Pa, close to standard atmospheric pressure), atmosphere (atm) (1 atm = 101,325 Pa), and psi (pounds per square inch, used in the US for tire and gas pressures). Blood pressure is measured in mmHg (millimetres of mercury), also called torr.

The millibar (symbol: mbar) is a non-SI unit of pressure equal to one-thousandth of a bar or exactly 100 pascals. It has been widely used in meteorology to report atmospheric pressure and remains common in weather forecasts, although the SI unit hectopascal has largely replaced it. One millibar is numerically equal to one hectopascal. More information is available in the bar (unit) reference.

One millibar is equal to 100 pascals, 1 hectopascal, 0.1 kilopascal, 0.001 bar, and 0.000986923 standard atmosphere. The millibar remains a familiar unit for atmospheric pressure worldwide.

Torr (symbol: Torr) is a unit of pressure defined as exactly 133.322368421 pascals, equivalent to one millimeter of mercury (mmHg) under standard conditions. The torr is widely used in vacuum technology, physics, analytical chemistry, and medical applications to measure low-pressure environments. It is commonly used to specify vacuum pump performance, laboratory vacuum systems, and pressure in scientific instruments. Torr is frequently converted to pascals, millimeters of mercury (mmHg), and standard atmospheres (atm) for engineering, laboratory, and industrial pressure measurements.
