About Kilopascals to Millimetres of Mercury
This converter turns kilopascals into millimetres of mercury as you type, and works the other way too: type in the millimetres of mercury box to convert back. To convert kilopascals to millimetres of mercury, multiply by 7.500615758. For example, 100 kPa is 750.0616 mmHg, and 220 kPa is 1,650.135 mmHg.
Pressure is quoted in different units for tyres, weather, blood pressure and engineering, so converting between bar, psi, kilopascals and millimetres of mercury is common. Both units have exact definitions, so the converter gives an exact result, rounded only for display. Use the table below for common values, or set the decimal places to round the answer for a form or a label.
How to use Kilopascals to Millimetres of Mercury
- Type the amount in kilopascals in the first box.
