How to Convert Pascal to Torr
- 1 Pa = 0.007500616827 Torr
- 1 Torr = 133.3223684 Pa
- Example: convert 15 Pa to Torr: 15 Pa = 15 × 0.007500616827 Torr = 0.1125092524 Torr
Formula
Torr = Pa × 0.007500616827042
or Torr = Pa ÷ 133.3223684211
Derivation from SI units:
- 1 Pa = 1 N/m² = 1 kg·m⁻¹·s⁻²
- 1 Torr = 101325/760 Pa = 133.3223684 Pa (1/760 of a standard atmosphere)
Both units are defined exactly, so the factor is exact. Pascal definition: pascal; Torr definition: torr.
Worked examples
- A rough vacuum of 1 Pa is 0.007500616827 Torr.
1 Pa × 0.007500616827 = 0.007500616827 Torr - Atmospheric pressure, 101325 Pa, is exactly 760 Torr.
101325 Pa × 0.007500616827 = 760 Torr

Frequently asked questions
Why is 1 atm exactly 760 Torr?
Because the torr is defined as 1/760 of a standard atmosphere, so 101 325 Pa = 760 Torr exactly and 1 Pa = 0.007500616827 Torr.
How many torr are in 1 pascal?
1 Pa = 0.007500616827 Torr.
How do I convert pascals to torr?
Multiply the value in Pa by 0.007500616827, or divide it by 133.3223684. For example, 15 Pa × 0.007500616827 = 0.1125092524 Torr.
Is the Pa to Torr conversion exact?
Yes. Both units are defined exactly, so the ratio is exact; its decimal form does not terminate and is shown here to 10 significant figures (more with the precision selector).
