Unit dP
Name decipoise
Category Dynamic Viscosity
Details A decipoise (dP) is a unit of dynamic viscosity, which is a measure of a fluid's resistance to flow or deformation. It is a subunit of the more commonly used Poise (P), where 1 Poise = 10 decipoise. Dynamic viscosity quantifies the internal resistance of a fluid to motion and is a critical property in many scientific, engineering, and industrial applications such as fluid dynamics, lubrication, and rheology.

The unit decipoise (dP) is derived from the CGS (centimeter-gram-second) system and is defined as the dynamic viscosity of a fluid in which a force of one dyne is required to move a surface of 1 square centimeter area at a speed of 1 centimeter per second when the surface is in contact with the fluid and separated by a distance of 1 centimeter.

The SI unit of dynamic viscosity is the Pascal-second (Pa·s), and the conversion factor is 1 dP = 0.001 Pa·s.
