About these units
Millimeters of Mercury (mmHg): A millimetre of mercury (mmHg) is about 133.32 Pa. Blood pressure is measured in mmHg.
Kilopascals (kPa): A kilopascal is 1,000 pascals. Tyre pressures in Canada and Australia are given in kPa.
Frequently asked questions
How many kilopascals are in 1 millimetre of mercury?
1 millimetre of mercury (mmHg) equals 0.1333223874 kilopascals (kPa).
How do I convert mmHg to kPa?
Multiply the value in millimetres of mercury by 0.1333223874. For example, 5 mmHg × 0.1333223874 = 0.6666119371 kPa.
How do I convert kilopascals back to millimetres of mercury?
Multiply by 7.500615758 (or divide by 0.1333223874). 1 kPa = 7.500615758 mmHg.
What is a millimetre of mercury?
A millimetre of mercury (mmHg) is about 133.32 Pa. Blood pressure is measured in mmHg.
