About Pound per foot-second (lb/(ft·s))
An imperial dynamic-viscosity unit (using pound-mass). Primarily encountered in US petroleum engineering, legacy ASME fluid-mechanics textbooks, and HVAC calculations where engineers prefer consistent US customary units throughout. 1 lb/(ft·s) ≈ 1.488 Pa·s. Most modern US engineering has migrated to centipoise or Pa·s, so this unit is most useful for interpreting older specifications and technical literature.
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.
