What is mmHg (mmHg)?
The millimetre of mercury (mmHg), also called torr, equals about 133.322 pascals. It survives mainly in medicine for blood pressure and in vacuum technology.
What is kPa (kPa)?
The kilopascal (kPa) equals 1,000 pascals and is the SI-based unit most used in science, engineering and many vehicle manuals outside the United States.
Why convert mmHg to kPa?
Pressure units differ by region and field: Europe uses bar, the US uses psi, science uses pascals and kilopascals, and medicine still uses mmHg. Converting between them is a daily need for mechanics, engineers and divers.
Standard atmospheric pressure is defined as exactly 101,325 Pa — equal to 1.01325 bar or 14.696 psi (BIPM/NIST). Car tyres are typically inflated to about 2.2–2.5 bar (32–36 psi).
