In practice
Millimetres of mercury to kilopascals multiplies by 0.133322, because 1 mmHg is 133.322 pascals. It is the conversion for blood pressure and barometric pressure, which are traditionally given in mmHg. A normal reading of 120/80 mmHg is 16/10.7 kPa, and standard atmospheric pressure of 760 mmHg is 101.3 kPa. Medical devices in the US display mmHg while many other countries and science publications use kPa. Use the conversion to understand a figure, not to interpret a health reading — follow a doctor's advice.
