The poiseuille (symbol Pl) has been proposed as a derived SI unit of dynamic viscosity, named after the French physicist Jean Léonard Marie Poiseuille (1797–1869). In practice the unit has never been widely accepted and most international standards bodies do not include the poiseuille in their list of units. The third edition of the IUPAC Green Book, for example, lists Pa⋅s (pascal-second) as the SI-unit for dynamic viscosity, and does not mention the poiseuille. The equivalent CGS unit, the poise, symbol P, is most widely used when reporting viscosity measurements.

| - Das Poiseuille (Einheitenzeichen: Pl), benannt nach dem französischen Physiker Jean Léonard Marie Poiseuille, war eine französische Einheit der dynamischen Viskosität und sollte nicht mit der CGS-Einheit Poise verwechselt werden.
* 1 Pl = 10 Poise = 1 Pascal · Sekunde Diese Einheit steht für Newtonsekunde pro Quadratmeter. (de)
- De poiseuille is een oude eenheid van dynamische viscositeit, met als symbool Pl. De poiseuille is gelijk aan 1 pascalseconde, die een eenheid is in het SI-stelsel. De poiseuille is vernoemd naar de Franse geneesheer en natuurkundige Jean Léonard Marie Poiseuille (1797-1869). Het is een oude Franse eenheid van dynamische viscositeit, die niet verward mag worden met de cgs-eenheid poise (P of Po). Beide zijn geen eenheid van het SI-stelsel meer. Eén poiseuille is tien poise. (nl)
- Il poiseuille (simbolo: Pl) è un'unità di misura della viscosità, ed è equivalente a un pascal per secondo. Nel sistema cgs si utilizza invece il poise, di simbolo P.Entrambe le unità di misura prendono il nome da Jean Léonard Marie Poiseuille, medico, fisiologo e fisico francese. (it)
- O pascal segundo (símbolo Pa·s) é a unidade do SI de viscosidade dinâmica. Se um fluido é colocado entre dois pratos, e um prato é empurrado lateralmente com uma tração de um pascal, ele move uma distância igual a espessura da camada entre os pratos em um segundo. Um pascal segundo equivale a 10 poises. O nome "poiseuille" foi proposto para esta unidade, mas foi rejeitada. (pt)

The equivalent CGS unit, the poise, symbol P, is most widely used when reporting viscosity measurements. Liquid water has a viscosity of 0.000890 Pl at 25 °C (77 °F) at a pressure of 1 atm (0.000890 Pl = 0.00890 P = 0.890 cP = 0.890 mPa⋅s). (en)
