About Centistoke (cSt)
A CGS kinematic-viscosity unit equal to 0.01 stoke (numerically identical to 1 mm²/s). Centistokes are the traditional unit in lubricant and petroleum industries — ISO VG viscosity grades (VG 10, VG 32, VG 68, etc.) refer to cSt at 40°C, and ASTM D445 (the standard viscosity test method) reports results in cSt. Marine fuel, diesel, and aviation kerosene specifications all use cSt.
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.

Understanding Centistokes
The Centistoke (symbol: cSt) is a unit of kinematic viscosity. A CGS kinematic-viscosity unit equal to 0.01 stoke (numerically identical to 1 mm²/s). Centistokes are the traditional unit in lubricant and petroleum industries — ISO VG viscosity grades (VG 10, VG 32, VG 68, etc.) refer to cSt at 40°C, and ASTM D445 (the standard viscosity test method) reports results in cSt. Marine fuel, diesel, and aviation kerosene specifications all use cSt.
It belongs to the metric measurement system.
Centistokes are commonly used in fluid flow analysis, lubrication engineering, and process design.
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.
Why Convert Centistokes to Square inches per second?
Converting between Centistokes and Square inches per second 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 Centistokes to Square inches per second?
A CGS kinematic-viscosity unit equal to 0. To convert Centistokes to Square inches per second, multiply by 0.00155. For example, 25 cSt equals 0.0387501 in²/s.
How many Square inches per second are in 1 Centistoke?
There are 0.00155 Square inches per second in 1 Centistoke.
How many Centistokes are in 1 Square inch per second?
There are 645.16 Centistokes in 1 Square inch per second.
What is the formula for Centistoke to Square inch per second conversion?
The formula is: multiply by 0.00155. This means 1 cSt = 0.00155 in²/s.
Is a Centistoke bigger than a Square inch per second?
Yes. One Centistoke is larger than one Square inch per second because 1 cSt equals 0.00155 in²/s, which is less than 1.
When do you need to convert between Centistokes and Square inches per second?
An imperial kinematic-viscosity unit (1/144 of ft²/s, about 645 cSt). Centistoke and Square inch per second are both kinematic viscosity units, so conversion comes up whenever one source of information uses one unit and another uses the other — a classic cross-reference challenge in engineering, trade, travel, and everyday life.
