Convert Kilopascals to Torr

Formula

Torr = kPa × 7.500616827042

Derivation from SI units:

• 1 kPa = 10³ Pa
• 1 Torr = 101325/760 Pa = 133.3223684 Pa (1/760 of a standard atmosphere)
• 1 kPa = 1000 Pa ÷ 133.3223684211 Pa per Torr = 7.500616827042 Torr

Both units are defined exactly, so the factor is exact. Kilopascal definition: kilopascal; Torr definition: torr.

Worked examples

1. A reading of 20 kPa converts to 150.0123365 Torr.
   20 kPa × 7.500616827 = 150.0123365 Torr
2. A value of 300 kPa is 2250.185048 Torr.
   300 kPa × 7.500616827 = 2250.185048 Torr

Where it's used

Kilopascals are used for tyre pressure outside the United States (about 200–250 kPa for cars), while torr appear in vacuum technology and vacuum gauges. Both measure pressure, stress and differential pressure (force per unit area), so the conversion is a fixed factor.
