Convert Millimeters of Mercury to Kilopascals
mmHg to kPa · pressure conversion
What are millimeters of mercury and kilopascals?
Millimeters of mercury measure pressure by the height of a mercury column, used for blood pressure. A kilopascal is 1,000 pascals, commonly used for tire and weather pressure. For reference: car tires run around 32 psi (220 kPa), and sea-level air pressure is about 101 kPa.
How to convert millimeters of mercury to kilopascals
1 mmHg = 0.133322 kPa. To convert, multiply the number of millimeters of mercury by 0.133322. For example, 5 mmHg = 0.66661 kPa, and 20 mmHg = 2.66644 kPa. To go the other way, multiply kilopascals by 7.50064 (since 1 kPa = 7.50064 mmHg).

FAQ
What is 1 mmHg in kPa?
1 mmHg = 0.133322 kPa. To convert any amount, multiply the number of millimeters of mercury by 0.133322.
How do I convert kilopascals back to millimeters of mercury?
Go the other way: 1 kPa = 7.50064 mmHg, so multiply kilopascals by 7.50064 to get millimeters of mercury.
Is a millimeters of mercury bigger than a kilopascal?
No — 1 mmHg is the smaller unit, equal to 0.133322 kPa (it takes 7.50064 mmHg to make one kPa).
Are these pressure conversions exact?
They use the standard internationally-defined conversion factors. Results are rounded to six significant figures for readability, which is accurate enough for everyday and most technical use.
