atm to dPa

atmosphere

• Definition: An atmosphere is a unit of pressure defined as being equal to the average pressure exerted by the Earth’s atmosphere at sea level.

• Symbol: The symbol for atmosphere is “atm.”

• Usage: The atmosphere is commonly used in various fields, including meteorology and aviation, to describe pressure conditions.

decipascal

• Definition: A decipascal is a unit of pressure equal to one-tenth of a pascal, which is the SI unit of pressure.

• Symbol: The symbol for decipascal is “dPa.”

• Usage: Decipascal is often used in scientific contexts to express small changes in pressure, particularly in fluid dynamics and material science.

Origin of the atmosphere

• The term “atmosphere” originates from the Greek word “atmos,” which means “vapor” or “steam,” and “sphaira,” meaning “sphere.” It was first used in the 17th century to describe the layer of gases surrounding the Earth.

Origin of the decipascal

• The decipascal is derived from the pascal, which was named after Blaise Pascal, a French mathematician, physicist, and inventor. The pascal was introduced as a unit of pressure in the 1970s as part of the SI system, with the decipascal being a convenient subunit for finer measurements.
