How to Convert Centistokes to Square Inches per Second
The centistokes and square inch per second are both units of viscosity. 1 square inch per second equals 645.16 centistokes. This means to convert centistokes to square inches per second, you divide by 645.16.
Formula
Step-by-Step Example
Convert 5 cSt to square inches per second:
We need to convert centistokes to square inches per second
Since 1 in²/s = 645.16 cSt, divide by 645.16
5 ÷ 645.16 = 0.0077500155
5 cSt = 0.0077500155 in²/s

About These Units
Centistokes (cSt)
The centistoke (cSt) is the most widely used kinematic viscosity unit, equal to 1 mm²/s. Water at 20°C: 1 cSt (reference). Motor oil grades: SAE 30 is 100 cSt at 40°C. ISO viscosity grades (VG 32, VG 46, etc.) specify cSt at 40°C. Standard for lubricant specifications worldwide.
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.
