Convert torr to exapascal
Please provide values below to convert torr [Torr] to exapascal [EPa], or Convert exapascal to torr.
How to Convert Torr to Exapascal
1 Torr = 1.33322368e-16 EPa
Example: convert 15 Torr to EPa:
15 Torr = 15 × 1.33322368e-16 EPa = 1.99983552e-15 EPa

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in fields like vacuum technology, physics, and medicine (e.g., blood pressure measurements), although it has largely been replaced by the pascal in most scientific contexts.
Exapascal
An exapascal (EPa) is a unit of pressure equal to 10^18 pascals, used to measure extremely high pressures.
History/Origin
The exapascal was introduced as part of the International System of Units (SI) prefixes to represent very large pressure values, primarily in scientific and engineering contexts involving high-pressure phenomena.
Current Use
The exapascal is mainly used in fields such as geophysics, astrophysics, and high-pressure physics to describe immense pressures found in planetary interiors, stellar environments, and experimental high-pressure research.
