Convert Torr to Micropascal (torr to Micropascal)

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

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.

The micropascal (symbol: µPa) is an SI-derived unit of pressure equal to one millionth (10^-6) of a pascal. It is commonly used in acoustics, sound pressure measurements, atmospheric science, and precision laboratory applications involving extremely small pressure variations. The micropascal uses the SI prefix micro, representing a factor of one millionth.

One micropascal is equal to 0.000001 pascal, 0.001 millipascal, 1,000 nanopascals, 1×10^-11 bar, and 9.86923×10^-12 standard atmosphere. The micropascal is particularly important in acoustics, where it is used as the reference unit for sound pressure levels.
