Convert Torr to Kilopascals

1 torr is 0.133322 kPa. One torr is exactly 0.133322368421 kilopascals.

One torr is 0.13332237 kilopascals. To convert torr to kilopascals, multiply by 0.13332237; to go the other way, divide by 0.13332237 or multiply by 7.5006168. The factor is exact rather than rounded: it follows from NIST Special Publication 811. Exactly one seven-hundred-and-sixtieth of a standard atmosphere.

How do you convert torr to kilopascals?

  1. 1.Take the measurement in torr.
  2. 2.Multiply by 0.13332237 — that is how many kilopascals fit in one torr.
  3. 3.To go back the other way, divide by 0.13332237, or multiply by 7.5006168.

Worked example: 25 torr to kilopascals

Formula
Torr × 0.13332237 = kPa
Arithmetic
25 × 0.13332237 = 3.333059 kPa
Answer
25 Torr = 3.333059 kPa

The factor is rounded for display; the figure above is computed from the full value.

What is a torr?

Exactly one seven-hundred-and-sixtieth of a standard atmosphere. Within a millionth of a millimetre of mercury, which is what it replaced, and still the unit of vacuum work.

What is a kilopascal?

A thousand pascals, and the unit metric tyre placards and weather stations use. Atmospheric pressure at sea level is about 101 kPa.

How many kilopascals are in a torr?

One torr is 0.13332237 kilopascals. Going the other way, one kilopascal is 7.5006168 torr. Both figures come from the same defined relation rather than from a measurement, which is why they are the same today as they were in 1959.
