Frequently Asked Questions
-
What does 1 hectopoise equal in pound/foot/hour?
-
1 hectopoise [hP] equals 24190.883105022 pound/foot/hour [lb/(ft*h)].
-

-
Hectopoise is used to describe very high viscosities such as those in bitumen, heavy crude oil, or polymer melts in material processing and formulation.
-
Why convert viscosity units from metric to imperial?
-
Converting units is essential when working with legacy systems, regional regulations, or US-based engineering data that use imperial units like pound/foot/hour.
Key Terminology
-
Hectopoise [hP]
-
A metric multiple of the poise used to measure dynamic viscosity; 1 hP equals 100 poise or 10 pascal-seconds.
-
Pound/foot/hour [lb/(ft*h)]
-
An imperial engineering unit expressing dynamic viscosity as force·time per unit area, relating shear stress to velocity gradient.
-
Dynamic Viscosity
-
A fluid's resistance to shear or flow, important in rheology and fluid mechanics contexts.
