Convert torr to nanopascal
Please provide values below to convert torr [Torr] to nanopascal [nPa], or Convert nanopascal to torr.
1 Torr = 133322368000 nPa. To convert torr to nanopascal, multiply the value by 133322368000; to go the other way, divide by it (1 nPa = 7.5006e-12 Torr). Both units measure pressure and appear in everyday as well as technical calculations, so switching between them quickly is often useful.
Quick Reference
- 1 Torr = 133322368000 nPa
- 1 nPa = 7.5006e-12 Torr
- 10 Torr = 1.3332e+12 nPa
- 100 Torr = 1.3332e+13 nPa
How to Convert Torr to Nanopascal
1 Torr = 133322368000 nPa
Example: convert 15 Torr to nPa:
15 Torr = 15 × 133322368000 nPa = 1999835520000 nPa

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in fields like vacuum technology, physics, and medicine (e.g., blood pressure measurements), although it has largely been replaced by the pascal in most scientific contexts.
Nanopascal
The nanopascal (nPa) is a unit of pressure equal to one billionth of a pascal, where 1 nPa = 10^-9 Pa.
History/Origin
The nanopascal was introduced as part of the SI unit system's extension to accommodate very small pressure measurements, primarily in scientific research involving micro- and nanoscale phenomena.
Current Use
Nanopascals are used in high-precision scientific applications such as atmospheric pressure measurements, microfluidics, and nanotechnology research where extremely low pressure differences need to be quantified.
