Formula
Step-by-Step Example
Convert 5 in²/s to pounds per foot second:
We need to convert square inches per second to pounds per foot second
Since 1 lb/(ft·s) = 2306.6588133 in²/s, divide by 2306.6588133
5 ÷ 2306.6588133 = 0.0021676374
5 in²/s = 0.0021676374 lb/(ft·s)

About These Units
Square Inch per Second (in²/s)
Square inches per second (in²/s) equals 6.45 stokes or 645 centistokes. Used for moderate viscosity materials in imperial units. Water at 20°C: 1.55×10⁻³ in²/s. One ft²/s = 144 in²/s. Common in smaller-scale US engineering applications.
Pound per Foot Second (lb/(ft·s))
Pounds per foot-second (lb/(ft·s)) is an imperial viscosity unit equal to 1.488 Pa·s. Uses mass rather than force. Also called pound-mass per foot-second. Water at 20°C: 6.7×10⁻⁴ lb/(ft·s). Common in US fluid mechanics textbooks.
