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.
