How to use
- Enter a value in the Kilopascals field.
- The Torr figure appears immediately — no button to press.
- Typing in the Torr field converts back to Kilopascals the same way.
- Use the reference table for the values that come up most often.
Kilopascals to Torr formula
To convert kilopascals to torr, multiply by 7.50061683.
Torr = kPa × 7.50061683
Why this factor: the kilopascal and the torr are both defined against the pascal, so dividing one definition by the other gives 7.50061683 directly. Both definitions are set out in full below.
To go the other way, divide by 7.50061683 — or use the Torr to Kilopascals converter, which is the same calculation reversed.
Worked example
Given 32 kPa, multiplying by 7.50061683 yields 240.019738 Torr.
32 kPa × 7.50061683 = 240.019738 Torr
The converter above does this for any value you type, in either direction.
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.
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.
Kilopascals vs Torr
The kilopascal 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.
