Convert Torr to Picopascal (torr to Picopascal)

Torr (torr) and Picopascal (Picopascal) are both units of pressure. With the conversion form below, you can effortlessly and accurately convert torr to picopascal. This free online calculator tool makes it simple and easy to perform the conversion from torr unit to the Picopascal 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 picopascal (symbol: pPa) is an SI-derived unit of pressure equal to one trillionth (10^-12) of a pascal. It is used in precision scientific research, acoustics, nanotechnology, and vacuum systems where extremely small pressure values need to be measured. The picopascal uses the SI prefix pico, representing one trillionth.

One picopascal is equal to 0.000000000001 pascal, 0.001 nanopascal, 1,000 femtopascals, 1×10^-17 bar, and 9.86923×10^-18 standard atmosphere. The picopascal provides a convenient SI unit for expressing extremely low pressure values.
