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 Millipascal-second (mPa·s)
A metric dynamic-viscosity unit equal to 0.001 Pa·s, numerically identical to the CGS centipoise. Convenient because water at room temperature is almost exactly 1 mPa·s — making mPa·s the natural unit for reporting viscosity of water-like fluids and dilute solutions. Pharmaceutical syrups, ink formulations, and biological fluids (blood plasma ~1.2–1.6 mPa·s) are commonly specified in mPa·s.
