How to Convert Pascal to Torr

1 pascal = 0.00750062 torr

Torr = Pascal × 0.00750062

Example: 542 Pa × 0.00750062 = 4.0653 Torr

Reverse Conversion

To convert torr back to pascals:

  • Remember, 1 torr equals 133.322 pascals.
  • To convert 4.0653 Torr to Pa, multiply 4.0653 x 133.322, resulting in 542 Pa.

542 Pa is also equal to:

  • 0.542 kPa
  • 0.00542 bar
  • 0.07861 psi
About these units

Pascal: SI derived unit of pressure equal to one newton per square meter (N/m²).

Torr: Pressure unit equal to exactly 1/760 of a standard atmosphere.
