Please provide values below to convert torr [Torr] to kilopascal [kPa], or Convert kilopascal to torr.
How to Convert Torr to Kilopascal
1 Torr = 0.133322368 kPa
Example: convert 15 Torr to kPa:
15 Torr = 15 × 0.133322368 kPa = 1.99983552 kPa

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in fields like vacuum technology, physics, and medicine (e.g., blood pressure measurements), although it has largely been replaced by the pascal in most scientific contexts.
Kilopascal
The kilopascal (kPa) is a unit of pressure equal to 1,000 pascals, where one pascal is defined as one newton per square meter.
History/Origin
The kilopascal was introduced as part of the metric system to provide a convenient unit for measuring pressure, especially in scientific and engineering contexts, replacing larger units like the bar in many applications.
Current Use
The kilopascal is widely used today in various fields such as meteorology, engineering, and physics to measure pressure, including tire pressure, blood pressure, and atmospheric pressure.
