About Millipascal-second (mPa·s)
A metric dynamic-viscosity unit equal to exactly 0.001 Pa·s, numerically identical to the CGS centipoise (1 mPa·s ≡ 1 cP exactly). The mPa·s is the most convenient working unit for water-like fluids and dilute aqueous solutions because water at 20 °C is essentially exactly 1 mPa·s — making the unit memorable and the conversion to viscosity ratios trivial. mPa·s is the universal reporting unit in: pharmacopoeial monographs (USP <911>, EP, JP) for ophthalmic solutions, parenteral preparations, and oral suspensions; clinical-laboratory biology and hematology (blood plasma 1.2-1.6 mPa·s, whole blood 3-4 mPa·s at body temperature — a clinically important parameter in stroke, sepsis, and polycythemia diagnostics); coatings industry rheometers reporting under ASTM D2196; printing-ink developers (ASTM D4287); food industry for fruit juices, syrups, dairy. Beer wort and finished beer 1.5-2.5 mPa·s; milk 2-3 mPa·s; honey 2,000-10,000 mPa·s.
About Pound per foot-hour (lb/(ft·hr))
An imperial dynamic-viscosity unit using pound-mass per foot-hour (≈ 4.1338 × 10⁻⁴ Pa·s = 0.4134 cP per NIST SP 811 = exactly 1/3,600 of lb/(ft·s)). Used in US process-engineering and HVAC contexts where the natural process timescale is hours rather than seconds — making the time-base of the viscosity unit match the time-base of the mass-flow or heat-flow calculation it appears in, eliminating intermediate unit conversions. Common in heat-transfer-coefficient correlations for gas-phase viscosity at industrial operating conditions (gas viscosity is ~10⁻⁵ Pa·s, which in lb/(ft·hr) becomes ~0.02 — a much more legible number than the SI version). Also appears in older US chemical-engineering handbooks (Perry's pre-2008 editions, McCabe-Smith-Harriott, Bird-Stewart-Lightfoot first edition), refining-process design references where the entire material/energy balance is in lb-h-ft-Btu units, and gas-pipeline transmission design per AGA Report No. 8 and 10 supercompressibility tables. Convert lb/(ft·hr) to Pa·s by multiplying by 4.1338 × 10⁻⁴; to cP by multiplying by 0.4134.
