How to Convert Pascal to Torr

1 pascal = 0.00750062 torr

Torr = Pascal × 0.00750062

Example: 991 Pa × 0.00750062 = 7.4331 Torr

Reverse Conversion

To convert torr back to pascals:

  • Remember, 1 torr equals 133.322 pascals.
  • To convert 7.4331 Torr to Pa, multiply 7.4331 x 133.322, resulting in 991 Pa.

991 Pa is also equal to:

  • 0.991 kPa
  • 0.00991 bar
  • 0.14373 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.
