Convert picopascal to torr
Please provide values below to convert picopascal [pPa] to torr [Torr], or Convert torr to picopascal.
1 pPa = 7.5006e-15 Torr. To convert picopascal to torr, multiply the value by 7.5006e-15; to go the other way, divide by it (1 Torr = 1.3332e+14 pPa). Both units measure pressure and appear in everyday as well as technical calculations, so switching between them quickly is often useful.
Quick Reference
- 1 pPa = 7.5006e-15 Torr
- 1 Torr = 1.3332e+14 pPa
- 10 pPa = 7.5006e-14 Torr
- 100 pPa = 7.5006e-13 Torr
How to Convert Picopascal to Torr
1 pPa = 7.5006168507298e-15 Torr
Example: convert 15 pPa to Torr:
15 pPa = 15 × 7.5006168507298e-15 Torr = 1.12509252760947e-13 Torr

Picopascal
The picopascal (pPa) is a unit of pressure equal to 10^-12 pascals, representing an extremely small pressure measurement.
History/Origin
The picopascal was introduced as part of the SI prefixes to measure very low pressures, primarily in scientific research and specialized fields requiring high precision. Its usage has been limited due to the small magnitude of the unit.
Current Use
Currently, the picopascal is rarely used in practical applications but may be employed in scientific experiments involving ultra-low pressure measurements or in theoretical contexts where extremely small pressure values are relevant.
Torr
The torr is a unit of pressure defined as 1 millimeter of mercury (mmHg) at standard gravity and temperature, approximately equal to 133.322 pascals.
History/Origin
The torr was introduced by Evangelista Torricelli in 1644, based on his experiments with mercury barometers, as a unit to measure atmospheric pressure. It was historically used in meteorology and physics before the adoption of the pascal.
Current Use
Today, the torr is primarily used in fields like vacuum technology, physics, and medicine (e.g., blood pressure measurements), although it has largely been replaced by the pascal in most scientific contexts.
