dekapoise [daP] Unit Converter

Definition of dekapoise [daP] unit

A dekapoise (daP) is a unit of dynamic viscosity equal to ten poise, or 1 pascal-second (Pa·s). It expresses a fluid’s resistance to shear and is equivalent to 1,000 centipoise.

History of dekapoise [daP] unit

The dekapoise derives from the poise, a centimetre-gram-second (CGS) unit named after French physicist Jean Léonard Marie Poiseuille, whose studies of liquid flow helped establish viscosity laws. In the CGS system, one poise equals one dyne-second per square centimetre. The SI system later replaced it with the pascal-second, while metric prefixes retained practical multiples such as the dekapoise. Although uncommon in modern technical standards, the unit appears in older engineering references, conversion tables, and some specialized viscosity documentation and laboratory literature.

Applications of dekapoise [daP] unit

A dekapoise is used to describe relatively viscous liquids in laboratory, chemical, petroleum, polymer, paint, and lubrication contexts. It may characterize oils, resins, coatings, adhesives, or concentrated solutions. Today, engineers generally report the same quantity in pascal-seconds or millipascal-seconds, but dekapoise values can still occur in legacy specifications, historical datasets, and unit-conversion software.
