What is Millimeter of mercury?

The millimeter of mercury is a unit of pressure based on the height of a mercury column, equal to approximately 133.3 pascals. It is the universal standard for reporting blood pressure in medicine: normal blood pressure is below 120 mmHg systolic and 80 mmHg diastolic. The unit originates from Torricelli's 1643 experiment, which showed that atmospheric pressure supports a mercury column of about 760 mm. One mmHg is nearly identical to one torr.

What is Kilopascal?

The kilopascal equals 1,000 pascals and is commonly used for tire pressure specifications. A typical passenger car tire is inflated to about 220 to 250 kPa. Some blood pressure monitors also display readings in kilopascals. In industry, gas pipeline pressures and hydraulic system pressures may be expressed in kPa. Standard atmospheric pressure is approximately 101.325 kPa.
