Bars to Torr formula
To convert bars to torr, multiply by 750.061683.
Torr = bar × 750.061683
Why this factor: the bar and the torr are both defined against the pascal, so dividing one definition by the other gives 750.061683 directly. Both definitions are set out in full below.
To go the other way, divide by 750.061683 — or use the Torr to Bars converter, which is the same calculation reversed.
Worked example
Given 760 bar, multiplying by 750.061683 yields 570046.878855 Torr.
760 bar × 750.061683 = 570046.878855 Torr
The converter above does this for any value you type, in either direction.
What is a bar?
A bar is a metric pressure unit chosen to sit very close to atmospheric pressure.
Definition: Exactly 100,000 pascals by definition. Standard atmosphere is 1.01325 bar, so a bar is slightly less.
Where it is used: European tire and hydraulic pressures, diving depth equivalents, and espresso machine ratings.
Worth knowing: Close to one atmosphere but not equal to it — the difference is about 1.3%.
What is a torr?
A torr is a vacuum-measurement pressure unit, defined as one 760th of a standard atmosphere.
Definition: Exactly 101,325/760 pascals, which is about 133.3224 Pa. Named after Evangelista Torricelli.
Where it is used: Vacuum systems, mass spectrometry, and semiconductor process chambers.
Worth knowing: Almost identical to the mmHg but not exactly equal — they differ by about one part in seven million, which matters only in precision metrology.
Bars vs Torr
The bar is a metric unit while the torr is a specialized unit. That is why the factor between them is not a round number: the two systems were defined independently and only later tied together by exact agreement.
