About Square inch per second (in²/s)
An imperial kinematic-viscosity unit (1/144 of ft²/s, about 645 cSt). In²/s is a specialty unit used in some US mechanical-engineering contexts — particularly older hydraulic fluid specifications and some mil-spec documents. Most modern US engineering has converged on cSt for kinematic viscosity reporting.
About Stoke (St)
The CGS unit of kinematic viscosity equal to 1 cm²/s (= 100 cSt = 10⁻⁴ m²/s). Named after Irish mathematician George Stokes, whose work on viscous fluid flow (Stokes' law) underpins modern fluid mechanics. Stokes are occasionally used in geophysics for highly viscous fluids like lava and mantle rock, where values of 10³ to 10¹⁵ stokes are typical.

Understanding Square inches per second
The Square inch per second (symbol: in²/s) is a unit of kinematic viscosity. An imperial kinematic-viscosity unit (1/144 of ft²/s, about 645 cSt). In²/s is a specialty unit used in some US mechanical-engineering contexts — particularly older hydraulic fluid specifications and some mil-spec documents. Most modern US engineering has converged on cSt for kinematic viscosity reporting.
It belongs to the imperial measurement system.
Square inches per second are commonly used in fluid flow analysis, lubrication engineering, and process design.
Understanding Stokes
The Stoke (symbol: St) is a unit of kinematic viscosity. The CGS unit of kinematic viscosity equal to 1 cm²/s (= 100 cSt = 10⁻⁴ m²/s). Named after Irish mathematician George Stokes, whose work on viscous fluid flow (Stokes' law) underpins modern fluid mechanics. Stokes are occasionally used in geophysics for highly viscous fluids like lava and mantle rock, where values of 10³ to 10¹⁵ stokes are typical.
It belongs to the metric measurement system.
Stokes are commonly used in fluid flow analysis, lubrication engineering, and process design.
Why Convert Square inches per second to Stokes?
Converting between Square inches per second and Stokes is a frequent requirement for engineers, scientists, and students working with kinematic viscosity values. Different industries and regions favour different unit systems, so having a dependable conversion tool saves time and prevents errors in technical calculations. Whether you are verifying a specification sheet, cross-checking simulation results, or preparing a report for an international audience, accurate kinematic viscosity conversion is essential.
Frequently Asked Questions
How do I convert Square inches per second to Stokes?
