How to Convert Pascal to Torr

1 pascal = 0.00750062 torr

Torr = Pascal × 0.00750062

Example: 661 Pa × 0.00750062 = 4.9579 Torr

Reverse Conversion

To convert torr back to pascals:

  • Remember, 1 torr equals 133.322 pascals.
  • To convert 4.9579 Torr to Pa, multiply 4.9579 x 133.322, resulting in 661 Pa.

661 Pa is also equal to:

  • 0.661 kPa
  • 0.00661 bar
  • 0.09587 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.
