Convert torr to hectopascal
Please provide values below to convert torr [Torr] to hectopascal [hPa], or Convert hectopascal to torr.
1 Torr = 1.33322368 hPa. To convert torr to hectopascal, multiply the value by 1.33322368; to go the other way, divide by it (1 hPa = 0.750061685073 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 = 1.33322368 hPa
- 1 hPa = 0.750061685073 Torr
- 10 Torr = 13.3322368 hPa
- 100 Torr = 133.322368 hPa
How to Convert Torr to Hectopascal
1 Torr = 1.33322368 hPa
Example: convert 15 Torr to hPa:
15 Torr = 15 × 1.33322368 hPa = 19.9983552 hPa

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in fields like vacuum technology, physics, and medicine (e.g., blood pressure measurements), although it has largely been replaced by the pascal in most scientific contexts.
Hectopascal
The hectopascal (hPa) is a unit of pressure equal to 100 pascals, commonly used in meteorology to measure atmospheric pressure.
History/Origin
The hectopascal was introduced as part of the metric system and became widely adopted in meteorology during the 20th century for standardizing atmospheric pressure measurements.
Current Use
Today, the hectopascal is predominantly used in weather reporting and forecasting to indicate atmospheric pressure, with standard sea-level pressure approximately 1013 hPa.
