dekapascal [daPa] Unit Converter

Definition of dekapascal [daPa] unit

The dekapascal (daPa) is a metric unit of pressure equal to 10 pascals. It represents a force of 10 newtons applied uniformly over an area of one square metre, and is one-tenth of a kilopascal.

History of dekapascal [daPa] unit

The dekapascal derives from the pascal, the SI unit named in honor of French mathematician and physicist Blaise Pascal, whose seventeenth-century experiments advanced understanding of pressure. The pascal was adopted within the modern International System of Units, formalized in 1960, as the coherent unit of pressure equal to one newton per square metre. The SI prefix “deka-,” meaning ten, comes from Greek deka and multiplies a unit by ten. Consequently, the dekapascal denotes ten pascals and follows standardized metric notation in scientific contexts.

Applications of dekapascal [daPa] unit

Today, dekapascals are used where pressures are conveniently expressed in tens of pascals, including meteorological measurements, HVAC and ventilation testing, cleanroom monitoring, and low-pressure laboratory work. They may describe small pressure differences across filters, ducts, membranes, or instruments. Although less common than pascals or kilopascals, daPa remains useful for precise, readable reporting.
