How to convert torr to kilopascals
This changes units only. Gauge and absolute pressures need a known ambient pressure to relate them; the converter does not add atmospheric pressure.
Use x for the value in Torr, b for the intermediate value in Pa, and y for the result in kPa.
kPa = Torr × 133.32236842105263 ÷ 1000
Worked examples
10 Torr ≈ 1.33322368421 kPa
Step 1: (10 × 133.322368421) ≈ 1333.22368421 Pa.
Step 2: 1333.22368421 ÷ 1000 ≈ 1.33322368421 kPa.20 Torr ≈ 2.66644736842 kPa
Step 1: (20 × 133.322368421) ≈ 2666.44736842 Pa.
Step 2: 2666.44736842 ÷ 1000 ≈ 2.66644736842 kPa.
Results are rounded to 12 significant digits. Converting units does not increase the precision of the original measurement. Very large or small values outside JavaScript’s finite numeric range are rejected.
About Torr
Torr (Torr) measures pressure under the conventions above. The base value in Pa is (x × 133.322368421), where x is the numerical value in Torr. Factors shown here are rounded for display; calculations use the stored factor.
About Kilopascals
Kilopascals (kPa) measures pressure under the conventions above. The base value in Pa is (x × 1000), where x is the numerical value in kPa. Factors shown here are rounded for display; calculations use the stored factor.
