How to Convert Manually
Use these steps to convert Torr values to Pascal without the calculator.
- Write down the value in Torr (torr) that you want to convert.
- Multiply that value by 133.3223684.
- For example, 10 Torrs × 133.3223684 = 1333.223684 Pascals.
- Label the result as Pascal (Pa).

About Torr and Pascal
The torr is exactly 1/760 of a standard atmosphere, about 133.32 pascals, named after Torricelli. Vacuum technology and laboratory work specify low pressures in torr. The pascal is the SI derived unit of pressure: one newton per square meter. It is small for everyday pressures, so kilopascals and hectopascals appear more often in practice. One Torr equals 133.3223684 Pascals (1 torr = 133.3223684 Pa). Torr is used in vacuum systems and coating and in laboratory low-pressure work. Pascal is used in physics and engineering calculations.
Precision and Rounding:Several pressure factors are exact by definition (1 atm = 101,325 Pa; 1 bar = 100,000 Pa) while others, like psi and mmHg, are derived and carry long decimals. Tire and weather readings tolerate whole-number rounding; calibration, medicine, and process engineering need the full factor before rounding.
Use the pressure conversion guide to compare mmHg, mbar, inHg, kPa, Pa, and torr across medical, weather, aviation, vacuum, and engineering work.
Conversion factors per NIST Special Publication 811 and the BIPM SI Brochure (9th edition) (reference).
