About Pound per foot-hour (lb/(ft·hr))
An imperial dynamic-viscosity unit used in some US process-engineering and HVAC contexts where timescales are naturally in hours rather than seconds. 1 lb/(ft·hr) ≈ 4.134 × 10⁻⁴ Pa·s. Found in some heat-transfer coefficient calculations and older US chemical engineering handbooks, particularly for gas-phase viscosity at industrial-operating conditions.
About Poise (P)
The CGS unit of dynamic viscosity, equal to 0.1 Pa·s. Named after French physician Jean Poiseuille, who studied blood flow in the 19th century. Although superseded by Pa·s in modern SI usage, poise still appears in older fluid-dynamics literature, geological rheology (rock/magma viscosities span 10¹⁰ to 10²¹ P), and some glass/polymer manufacturing tables.

Understanding Pounds per foot-hour
The Pound per foot-hour (symbol: lb/(ft·hr)) is a unit of dynamic viscosity. An imperial dynamic-viscosity unit used in some US process-engineering and HVAC contexts where timescales are naturally in hours rather than seconds. 1 lb/(ft·hr) ≈ 4.134 × 10⁻⁴ Pa·s. Found in some heat-transfer coefficient calculations and older US chemical engineering handbooks, particularly for gas-phase viscosity at industrial-operating conditions.
It belongs to the imperial measurement system.
Pounds per foot-hour are commonly used in lubricant selection, chemical processing, and fluid dynamics.
Understanding Poise
The Poise (symbol: P) is a unit of dynamic viscosity. The CGS unit of dynamic viscosity, equal to 0.1 Pa·s. Named after French physician Jean Poiseuille, who studied blood flow in the 19th century. Although superseded by Pa·s in modern SI usage, poise still appears in older fluid-dynamics literature, geological rheology (rock/magma viscosities span 10¹⁰ to 10²¹ P), and some glass/polymer manufacturing tables.
It belongs to the metric measurement system.
Poise are commonly used in lubricant selection, chemical processing, and fluid dynamics.
