lb/(ft·s)
pound per foot second
Dynamic viscosityexact by definition
The pound per foot second is exactly 1.4881639435695537 Pa·s. It is the viscosity unit that appears when the pound is used for mass rather than force, and it is 32.174 times larger than the pound-force second per square foot.
Watch out: This unit and lbf·s/ft² are both routinely written "lb/ft·s" in careless typesetting and differ by the factor 32.174. Which one a table means can usually be settled by checking water: 6.72 × 10⁻⁴ lb/(ft·s) on this convention, 2.09 × 10⁻⁵ lbf·s/ft² on the other.
