How to Convert Pascal to Torr

1 pascal = 0.00750062 torr

Torr = Pascal × 0.00750062

Example: 400 Pa × 0.00750062 = 3.0002 Torr

Reverse Conversion

To convert torr back to pascals:

  • Remember, 1 torr equals 133.322 pascals.
  • To convert 3.0002 Torr to Pa, multiply 3.0002 x 133.322, resulting in 400 Pa.

400 Pa is also equal to:

  • 0.4 kPa
  • 0.004 bar
  • 0.058015 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.
