Torr (Torr) to Kilopascals (kPa) Conversion
Torr
The torr is a unit of pressure named after Evangelista Torricelli, the Italian physicist who invented the mercury barometer in 1643. One torr is defined as exactly 1/760 of a standard atmosphere (approximately 133.322 Pa). Numerically nearly identical to the millimetre of mercury (mmHg), it differs by less than 0.000015%. The torr is used in vacuum science and engineering: rough vacuum is 1–100 torr, fine vacuum 10⁻³–1 torr, and ultra-high vacuum below 10⁻⁹ torr.
Kilopascals
The kilopascal (kPa) is a unit of pressure equal to exactly 1,000 pascals and is one of the most practical pressure units for everyday engineering. Standard atmospheric pressure is approximately 101.3 kPa. Tyre pressure is commonly specified in kPa in metric countries: a typical car tyre is inflated to 220–250 kPa. Blood pressure in clinical settings is measured in mmHg, but some medical devices express it in kPa (normal systolic ≈ 16 kPa).
