TORR Meaning and
Definition
-
A torr is a unit of measurement used to quantify the pressure exerted by a gas or vapor. It is equivalent to the pressure exerted by a column of mercury that is 1 millimeter in height at 0 degrees Celsius under standard gravitational force. The torr is named after Evangelista Torricelli, an Italian physicist who invented the mercury barometer.
The torr is commonly used in scientific and engineering contexts, especially in fields such as chemistry and physics where precise pressure measurements are critical. It is also occasionally used in meteorology and medicine.
In terms of conversion, one torr is equal to approximately 1/760th of standard atmospheric pressure, or about 133.3 pascals. It is also equivalent to 1 millimeter of mercury (mmHg) or 1.33322 hectopascals (hPa).
The torr provides a convenient way to express pressure in a smaller range compared to atmospheric pressure, allowing for more precise measurements in a controlled environment. It is widely utilized in laboratories, industrial settings, and research facilities, where the ability to accurately measure and control pressure is essential for experiments and processes. The torr has remained a relevant unit of pressure measurement, providing a valuable reference point for scientific and technological advancements.
