Convert Millimeters of Mercury to Pascals
mmHg to Pa · pressure conversion
What are millimeters of mercury and pascals?
Millimeters of mercury measure pressure by the height of a mercury column, used for blood pressure. The pascal is the SI unit of pressure, one newton per square meter. 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 pascals
1 mmHg = 133.322 Pa. To convert, multiply the number of millimeters of mercury by 133.322. For example, 5 mmHg = 666.61 Pa, and 20 mmHg = 2,666.44 Pa. To go the other way, multiply pascals by 0.00750064 (since 1 Pa = 0.00750064 mmHg).
