About Pound per foot-second (lb/(ft·s))
An imperial dynamic-viscosity unit using pound-mass per foot-second (≈ 1.4882 Pa·s per NIST SP 811 = 1,488 cP). Primarily encountered in US petroleum engineering (older API and SPE journal articles quote downhole-fluid viscosities in lb/(ft·s) alongside cP for drilling-fluid rheology and well-cementing calcs per API RP 13B), legacy ASME fluid-mechanics and heat-transfer textbooks (older editions of Streeter, McCabe-Smith-Harriott, Bird-Stewart-Lightfoot, Incropera-DeWitt), and HVAC calculations performed in fully-imperial unit systems where consistency with lb / ft / s eliminates conversion factors in Reynolds-number and Prandtl-number dimensionless-group formulas. Most modern US engineering has migrated to centipoise / Pa·s for new work; lb/(ft·s) is most useful for interpreting pre-1990s US-edition specifications, journal articles, and ASME-code background calculation derivations. Convert lb/(ft·s) to Pa·s by multiplying by 1.4882; to cP / mPa·s by multiplying by 1,488.2; to lb/(ft·hr) by multiplying by 3,600.
About Centipoise (cP)
A CGS dynamic-viscosity unit equal to exactly 0.01 poise = 0.001 Pa·s = 1 mPa·s. Centipoise is the traditional working unit in coatings, paints, petroleum products, food processing, and pharmaceutical excipient characterization — Brookfield rotational viscometers (the industry-standard QC instrument since the 1930s) default to reporting in cP on the dial readout. Test methods: ASTM D445 (kinematic viscosity, but cross-references to cP via density), ASTM D2196 (rheological properties via rotational viscometer), ASTM D562 (Stormer viscometer Krebs Units, with cP cross-reference), ISO 2555 (Brookfield-method paint and ink), USP <911> (pharmacopoeial Brookfield method). Reference values: water = 1 cP at 20 °C (the famous calibration baseline; viscosity standards are sold traceable to NIST in mPa·s / cP units), SAE 10W30 motor oil at 100 °C ~12 cP, latex paint 500-1,500 cP, ketchup ~50,000 cP (highly shear-thinning so the exact number depends on shear rate).

Understanding Pounds per foot-second
The Pound per foot-second (symbol: lb/(ft·s)) is a unit of dynamic viscosity. An imperial dynamic-viscosity unit using pound-mass per foot-second (≈ 1.4882 Pa·s per NIST SP 811 = 1,488 cP). Primarily encountered in US petroleum engineering (older API and SPE journal articles quote downhole-fluid viscosities in lb/(ft·s) alongside cP for drilling-fluid rheology and well-cementing calcs per API RP 13B), legacy ASME fluid-mechanics and heat-transfer textbooks (older editions of Streeter, McCabe-Smith-Harriott, Bird-Stewart-Lightfoot, Incropera-DeWitt), and HVAC calculations performed in fully-imperial unit systems where consistency with lb / ft / s eliminates conversion factors in Reynolds-number and Prandtl-number dimensionless-group formulas. Most modern US engineering has migrated to centipoise / Pa·s for new work; lb/(ft·s) is most useful for interpreting pre-1990s US-edition specifications, journal articles, and ASME-code background calculation derivations. Convert lb/(ft·s) to Pa·s by multiplying by 1.4882; to cP / mPa·s by multiplying by 1,488.2; to lb/(ft·hr) by multiplying by 3,600.
