kPa to atm

kilopascal

• Definition: The kilopascal (kPa) is a unit of pressure. It is equal to one thousand pascals, where a pascal is defined as one newton per square meter.

• Symbol: The symbol for kilopascal is “kPa.”

• Usage: Kilopascals are commonly used in various fields such as meteorology, engineering, and environmental science to measure pressure, including atmospheric pressure and tire pressure.

atmosphere

• Definition: An atmosphere (atm) is a unit of pressure defined as being precisely equal to 101.325 kilopascals, which is approximately equal to the average atmospheric pressure at sea level on Earth.

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

• Usage: The atmosphere is frequently used in various scientific contexts, particularly in chemistry and physics, to express pressures in gas laws and other calculations.

Origin of the kilopascal

• The kilopascal was introduced as part of the International System of Units (SI) and is derived from Blaise Pascal, a French mathematician, physicist, and inventor who made significant contributions to fluid mechanics. It provides a more practical unit for measuring pressure in everyday applications by scaling up the pascal.

Origin of the atmosphere

• The atmosphere unit originated from early studies of atmospheric pressure and was defined based on the weight of the air above a unit area at sea level. The unit was formalized in the 19th century and has since been used as a standard reference in many scientific fields.
