About Torr (torr)
A unit of pressure equal to 1/760 of a standard atmosphere (about 133.322 Pa), numerically almost identical to one mmHg. Named after 17th-century physicist Evangelista Torricelli, who invented the mercury barometer. Torr is the primary unit in vacuum technology: semiconductor chamber pressure, mass spectrometry, cryogenic systems, and space environment testing. A "rough vacuum" is ~1 torr, high vacuum is 10⁻⁶ torr, ultrahigh vacuum is 10⁻⁹ torr or lower.
About Pascal (Pa)
The SI derived unit of pressure equal to one newton per square meter (N/m²). Named for 17th-century French mathematician Blaise Pascal, whose work on fluid statics underpins modern pressure theory. The pascal is a small unit — atmospheric pressure is ~101,325 Pa — so engineering and meteorology usually work in kPa, MPa, or hPa. The pascal is the universal SI reference for pressure, used in scientific publication, thermodynamic state tables, and international engineering standards.

Understanding Torr
The Torr (symbol: torr) is a unit of pressure. A unit of pressure equal to 1/760 of a standard atmosphere (about 133.322 Pa), numerically almost identical to one mmHg. Named after 17th-century physicist Evangelista Torricelli, who invented the mercury barometer. Torr is the primary unit in vacuum technology: semiconductor chamber pressure, mass spectrometry, cryogenic systems, and space environment testing. A "rough vacuum" is ~1 torr, high vacuum is 10⁻⁶ torr, ultrahigh vacuum is 10⁻⁹ torr or lower.
Torr are commonly used in tire inflation, weather reporting, scuba diving, and engineering.
Understanding Pascals
The Pascal (symbol: Pa) is a unit of pressure. The SI derived unit of pressure equal to one newton per square meter (N/m²). Named for 17th-century French mathematician Blaise Pascal, whose work on fluid statics underpins modern pressure theory. The pascal is a small unit — atmospheric pressure is ~101,325 Pa — so engineering and meteorology usually work in kPa, MPa, or hPa. The pascal is the universal SI reference for pressure, used in scientific publication, thermodynamic state tables, and international engineering standards.
It belongs to the metric measurement system.
Pascals are commonly used in tire inflation, weather reporting, scuba diving, and engineering.
Why Convert Torr to Pascals?
Engineers, mechanics, and scientists frequently need to convert pressure between Torr and Pascals when working with different measurement standards. Tire pressure, blood pressure readings, weather barometric measurements, and industrial process specifications may all use different pressure units depending on the region or discipline. Reliable conversion prevents equipment misuse and ensures safety.
Frequently Asked Questions
How do I convert Torr to Pascals?
A unit of pressure equal to 1/760 of a standard atmosphere (about 133. To convert Torr to Pascals, multiply by 133.322. For example, 25 torr equals 3333.05 Pa.
How many Pascals are in 1 Torr?
There are 133.322 Pascals in 1 Torr.
How many Torr are in 1 Pascal?
There are 0.00750064 Torr in 1 Pascal.
What is the formula for Torr to Pascal conversion?
The formula is: multiply by 133.322. This means 1 torr = 133.322 Pa.
Is a Torr bigger than a Pascal?
No. One Torr is smaller than one Pascal because 1 torr equals 133.322 Pa, which is greater than 1.
When do you need to convert between Torr and Pascals?
The SI derived unit of pressure equal to one newton per square meter (N/m²). Torr and Pascal are both pressure units, so conversion comes up whenever one source of information uses one unit and another uses the other — a classic cross-reference challenge in engineering, trade, travel, and everyday life.
