Pa to dPa

pascal

• Definition: The pascal is the SI unit of pressure, defined as one newton per square meter. It quantifies the internal pressure, stress, and tensile strength of materials.

• Symbol: The symbol for pascal is “Pa”.

• Usage: Pascals are commonly used in various fields, including engineering, meteorology, and physics, to measure pressure, stress, and tensile strength.

decipascal

• Definition: The decipascal is a derived metric unit of pressure that is equal to one-tenth of a pascal.

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

• Usage: Decipascals are used in scenarios requiring finer measurements of pressure, particularly in scientific research and various engineering applications.

Origin of the pascal

• The pascal is named after Blaise Pascal, a French mathematician, physicist, and inventor who made significant contributions to fluid mechanics and pressure measurement. It was adopted as an SI unit in 1971.

Origin of the decipascal

• The decipascal is a subunit of the pascal, created by the metric system to offer a more precise scale for pressure measurements. The “deci-” prefix denotes a factor of one-tenth, following the International System of Units (SI) conventions.
