Kilopascals (kPa)
Definition
A kilopascal (kPa) is a unit of pressure equal to 1,000 pascals. It provides a practical scale for many common pressure measurements.
History
The kilopascal became widely used with the adoption of SI units in the 20th century. It offered a convenient alternative to the bar and atmosphere for expressing everyday pressures.
Current use
Kilopascals are commonly used for tire pressure specifications (outside the US), blood pressure in some countries, weather station atmospheric pressure reports, and industrial process pressures.
Millimeters of Mercury (mmHg)
Definition
Millimeters of mercury (mmHg) is a unit of pressure based on the height of a mercury column, equal to approximately 133.322 pascals. It is nearly identical to the torr.
History
Millimeters of mercury originated from Torricelli's mercury barometer in the 17th century. Measuring pressure by mercury column height became the standard method for centuries and remains in medical practice.
Current use
mmHg is the standard unit for measuring blood pressure worldwide (e.g., 120/80 mmHg). It is also used in measuring intraocular pressure, cerebrospinal fluid pressure, and in some vacuum applications.
