dPa to Torr

decipascal

• Definition: The decipascal (dPa) is a unit of pressure that is equal to one-tenth of a pascal. It is used in various fields, particularly where smaller pressure measurements are necessary.

• Symbol: The symbol for decipascal is dPa.

• Usage: Decipascal is often used in meteorology and engineering applications where precise measurements of low pressure are required.

torr

• Definition: The torr is a unit of pressure defined as 1/760 of an atmosphere. It is commonly used in the fields of physics and engineering, particularly in vacuum measurements.

• Symbol: The symbol for torr is Torr.

• Usage: Torr is widely used in laboratory settings and industries that require vacuum technology.

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 is a standard unit of pressure in the International System of Units (SI) and is defined as one newton per square meter.

Origin of the torr

• The torr is named after Evangelista Torricelli, an Italian physicist and mathematician who invented the barometer. The unit was established based on the height of a column of mercury that would balance atmospheric pressure.
