Torr to Pascal: The Essentials
What is Torr?
Torr (Torr) is a unit of pressure measurement. 1 torr is equal to 133.3223684 pascal.
About the Pascal
Pascal (Pa) is a unit of pressure measurement. 1 pascal is equal to 0.0075006 torr.
Pressure Units Across Industries
Pressure measurements vary dramatically by industry. Meteorologists report in millibars or hectopascals, tire shops use PSI, scuba divers think in atmospheres or bar, vacuum engineers work in torr, and hydraulic systems specify in megapascals. A single industrial plant might encounter all these units across different equipment manuals, safety datasheets, and regulatory standards from different countries.

How to Convert Torr to Pascal (Step-by-Step)
Converting torr to pascals is standard when translating vacuum research data into SI units for publication. The conversion factor is 1 torr = 133.322 Pa (approximately).
- Write down the pressure value in torr.
- Multiply the torr value by 133.322.
- The result is the equivalent pressure in pascals (Pa).
- For precise scientific work, use the exact value: 1 torr = 101325/760 Pa = 133.32236842... Pa.

Solved Examples: Torr to Pascal
Question 1: A vacuum gauge reads 5 × 10⁻³ torr in a sputtering chamber. Express in Pa for publication.
Solution:
Pressure in Pa = Pressure in torr × 133.322
= 5 × 10⁻³ × 133.322
= 0.6666 Pa
Answer: 5 × 10⁻³ torr = 0.667 Pa — typical base pressure for magnetron sputtering.
Question 2: A rotary evaporator operates at 20 torr. Convert to Pa.
Solution:
Pressure in Pa = 20 × 133.322

Answer: 20 torr = 2666 Pa ≈ 2.67 kPa — suitable for low-boiling-point solvent removal.
Question 3: The base pressure of a turbomolecular pump is 10⁻⁸ torr. Express in Pa.
Solution:
Pressure in Pa = 10⁻⁸ × 133.322
= 1.33 × 10⁻⁶ Pa
Answer: 10⁻⁸ torr = 1.33 × 10⁻⁶ Pa = 1.33 μPa — ultra-high vacuum territory.

SI Unit Policy in Vacuum Science Publications
Major scientific journals (Nature, Physical Review, Journal of Vacuum Science & Technology) require or prefer SI units (Pa or mPa). However, the vacuum community historically published in torr, and many instrument readouts still display torr. When writing papers, state the pressure in Pa with torr in parentheses for reference: "base pressure of 1.33 × 10⁻⁵ Pa (10⁻⁷ torr)." This convention bridges modern SI requirements with the intuitive torr scale familiar to experimentalists.
Vacuum Gauge Types and Their Native Units
Different vacuum gauges historically read in different units: Bourdon gauges (mbar/torr), thermocouple gauges (torr or mbar), Pirani gauges (torr or Pa), capacitance manometers (torr or Pa), ionization gauges (torr or Pa). Modern digital controllers allow selecting display units, but analog gauges have fixed scales. When converting readings for data logging or publication, the torr-to-Pa factor (133.322) is applied constantly in vacuum laboratories worldwide.
Key Takeaways
- Multiply torr by 133.322 to get pascals.
