Convert Pounds per foot-second to Slugs per foot-second
Convert Pounds per foot-second (lb/(ft·s)) to Slugs per foot-second (slug/(ft·s)) instantly and accurately.
Conversion Formula
slug/(ft·s) = lb/(ft·s) × 0.03108095017
About Pounds per foot-second
The pound per foot-second (lb/(ft·s)) equals 0.45359237/0.3048 ≈ 1.4882 Pa·s, the absolute viscosity unit in the foot-pound-second (FPS) system. It appears in legacy US chemical engineering textbooks and fluid mechanics problems stated in USC units. A heavy fuel oil at 50 °C with viscosity 0.050 Pa·s = 0.0336 lb/(ft·s). 1 lb/(ft·s) ≈ 1.4882 Pa·s = 14.882 P.
About Slugs per foot-second
The slug per foot-second (slug/(ft·s)) equals 1 lbf·s/ft² ≈ 47.880 Pa·s, the coherent FPS viscosity unit where force is in pound-force. It is used in US aerospace and hydraulic engineering when working with the slug as the unit of mass. Water at 20 °C has a viscosity of ≈2.09×10⁻⁵ slug/(ft·s); hydraulic fluid MIL-PRF-5606 is ≈3×10⁻⁴ slug/(ft·s) at 100 °F. 1 slug/(ft·s) ≈ 47.880 Pa·s.
