How to Convert Torr to Pascal
- 1 Torr = 133.3223684 Pa
- 1 Pa = 0.007500616827 Torr
- Example: convert 15 Torr to Pa: 15 Torr = 15 × 133.3223684 Pa = 1999.835526 Pa
Formula
Pa = Torr × 133.3223684211
Derivation from SI units:
- 1 Torr = 101325/760 Pa = 133.3223684 Pa (1/760 of a standard atmosphere)
- 1 Pa = 1 N/m² = 1 kg·m⁻¹·s⁻²
Both units are defined exactly, so the factor is exact. Torr definition: torr; Pascal definition: pascal.
Worked examples
- A high-vacuum chamber at 0.001 Torr is at 0.1333223684 Pa.
0.001 Torr × 133.3223684 = 0.1333223684 Pa - 760 Torr is exactly 101325 Pa, one standard atmosphere.
760 Torr × 133.3223684 = 101325 Pa
