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.

Millipoise (mP)

A millipoise (mP) equals 0.001 poise or 0.1 cP. Used for low-viscosity fluids and gases. Air at 20°C: 0.18 mP, water at 100°C: 2.8 mP, acetone: 3.1 mP. Provides finer resolution than centipoise for thin fluids and gases.
