mmHg to dPa

millimeter of mercury

• Definition: A millimeter of mercury (mmHg) is a unit of pressure that is defined as the pressure exerted by a column of mercury exactly one millimeter high at standard gravity.

• Symbol: The symbol for millimeter of mercury is mmHg.

• Usage: This unit is commonly used in medicine and meteorology, particularly for measuring blood pressure and atmospheric pressure.

decipascal

• Definition: A decipascal (dPa) is a unit of pressure in the International System of Units (SI), equal to one-tenth of a pascal.

• Symbol: The symbol for decipascal is dPa.

• Usage: Decipascal is often used in fields that require precise measurements of pressure, such as physics and engineering.

Origin of the millimeter of mercury

• The millimeter of mercury originated from the use of mercury barometers in the 17th century, where the height of mercury in a glass tube was used to measure atmospheric pressure. This unit became standardized due to its practical application in various scientific and medical fields.

Origin of the decipascal

• The decipascal is derived from the pascal, which is named after Blaise Pascal, a French mathematician, physicist, and inventor. The pascal was established as the SI unit of pressure in 1983, and the decipascal provides a smaller scale for measuring pressure with greater precision.
