decP

decP refers to a unit of pressure equal to one-tenth of a pascal. The pascal (Pa) is the SI derived unit of pressure, defined as one newton per square meter (N/m²). Therefore, decP is equivalent to 0.1 N/m². This unit is not commonly used in scientific literature or everyday applications, with the pascal, kilopascal (kPa), or megapascal (MPa) being the more standard prefixes for pressure measurements. While decP is a mathematically valid prefix combination, its practical utility is limited. For context, atmospheric pressure at sea level is approximately 101,325 pascals, which would translate to 1,013,250 decP. Similarly, a typical tire pressure of 30 psi is roughly 206,843 pascals, or 2,068,430 decP. The dec prefix, meaning one-tenth, is less frequently employed compared to other SI prefixes like kilo, mega, or milli, contributing to the rarity of decP as a standalone unit of measurement.
