FAQs
Why 133.322?
It comes from 101,325 Pa per atmosphere divided by 760 Torr per atmosphere.
Is Torr the same as mmHg?
They are close but not exact; 1 Torr is defined from standard atmosphere, while mmHg depends on mercury density and gravity. Use Torr for reproducible calculations.
How do I go back to Pa?
Multiply Torr by 133.322 to return to Pascals.
