Torr to Kilopascals formula
The factor from torr to kilopascals is 0.133322368.
kPa = Torr × 0.133322368
Why this factor: the torr and the kilopascal are both defined against the pascal, so dividing one definition by the other gives 0.133322368 directly. Both definitions are set out in full below.
To go the other way, divide by 0.133322368 — or use the Kilopascals to Torr converter, which is the same calculation reversed.
Worked example
Start with 760 Torr. Multiply by 0.133322368 to get 101.325 kPa.
760 Torr × 0.133322368 = 101.325 kPa
The converter above does this for any value you type, in either direction.
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.
What is a kilopascal?
A kilopascal is 1,000 pascals, the practical metric pressure unit.
Definition: Exactly 1,000 pascals. Standard atmospheric pressure is 101.325 kPa.
Where it is used: Tyre pressures outside the US, weather reports in Canada, and structural engineering loads.
Torr vs Kilopascals
The torr is a specialized unit while the kilopascal is a metric 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.
