Millimeters of Mercury to Kilopascals Converter

To convert a measurement in millimeters of mercury to kilopascals, multiply the value by 0.133322387415. The conversion factor comes from the relationship between both units and the pascal.

For example, to convert 5 mmHg to kilopascals: 5 × 0.133322387415 = 0.666611937075 kPa.

A millimeter of mercury (mmHg) is a unit of pressure equal to the pressure exerted by a one-millimeter-high column of mercury, about 133.32 pascals. Derived from early mercury barometers, the mmHg is nearly identical to the torr. It remains the standard unit for blood pressure and other physiological measurements in medicine worldwide.

Common uses of millimeters of mercury include: Blood pressure readings (systolic/diastolic); Intraocular and intracranial pressure; Barometric pressure in medicine; Vacuum and gas-pressure measurement.

A kilopascal equals 1,000 pascals and is the most common metric unit for everyday pressures such as tire inflation. The kilopascal became widespread as metric countries standardized on SI units, replacing older units like the kilogram-force per square centimeter in engineering and automotive specifications.

Common uses of kilopascals include: Tire pressure in metric countries; Blood pressure in some clinical contexts; HVAC and building pressure specifications; Compressed air and pneumatic systems.

Here are some common values converted:

1 mmHg = 0.133322387415 kPa 5 mmHg = 0.666611937075 kPa 10 mmHg = 1.333224 kPa 50 mmHg = 6.666119 kPa 100 mmHg = 13.332239 kPa
