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 Although superseded by Pa·s in modern SI usage, poise still appears in older fluid-dynamics literature, geological rheology (rock/magma viscosities span 10¹⁰ to 10²¹ P), and some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 Although superseded by Pa·s in modern SI usage, poise still appears in older fluid-dynamics literature, geological rheology (rock/magma viscosities span 10¹⁰ to 10²¹ P), and some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.

Why Convert Pounds per foot-hour to Poise?

Converting between Pounds per foot-hour and Poise is a frequent requirement for engineers, scientists, and students working with dynamic viscosity values. Different industries and regions favour different unit systems, so having a dependable conversion tool saves time and prevents errors in technical calculations. Whether you are verifying a specification sheet, cross-checking simulation results, or preparing a report for an international audience, accurate dynamic viscosity conversion is essential.
