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 Torr × 133.3223684 = 1333.223684 Pascal.
- 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 Pascal (1 torr = 133.3223684 Pa). Torr to Pascal conversion comes up most often in vacuum systems and coating and in laboratory low-pressure work, typically when figures need restating for 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.
Conversion factors per NIST Special Publication 811 and the BIPM SI Brochure (9th edition) (reference).
