About Stoke (St)
The CGS unit of kinematic viscosity equal to exactly 1 cm²/s (= 100 cSt = 10⁻⁴ m²/s). Named after Irish mathematician Sir George Gabriel Stokes, whose 1851 paper 'On the Effect of the Internal Friction of Fluids on the Motion of Pendulums' (Cambridge Phil. Trans.) established the laminar-drag formula F = 6πμrv (Stokes' law) — still the basis for terminal-velocity calculations for sedimenting particles, atmospheric aerosol settling rates, and laboratory particle-sizing techniques (Stokes diameter). The stoke as a unit is occasionally used directly for highly viscous fluids in geophysics and glass science where typical values are large enough that cSt would have many leading zeros: basaltic lava 10² to 10⁴ St at eruption temperature, granitic / rhyolitic lava 10⁹ to 10¹¹ St, the asthenosphere of Earth's mantle 10¹⁸ to 10²⁰ St, the lower mantle 10²² St, glass at the working point ~10⁴ St.
About Centistoke (cSt)
A CGS kinematic-viscosity unit equal to exactly 0.01 stoke = 1 mm²/s = 10⁻⁶ m²/s. Centistokes is the traditional and still-dominant working unit in the global lubricant industry, petroleum products, and fuel-oil specifications. Industry standards using cSt directly: ISO 3104 / ASTM D445 (the universal capillary-tube kinematic-viscosity test method — every lubricant data sheet in the world traces back to this test), ISO 8217 (marine fuels — DM and RM grades all spec viscosity in cSt at either 40 °C or 50 °C; e.g., MGO 'Marine Gas Oil' is ≤ 6.0 cSt at 40 °C; HFO 'Heavy Fuel Oil' is up to 700 cSt at 50 °C), ASTM D2270 (Viscosity Index calculation from kinematic viscosity at 40 / 100 °C), SAE J300 (engine-oil grading at 100 °C and CCS-tested low-temp cP), ISO VG industrial-lubricant grading (the VG number = cSt at 40 °C, ±10%).

Understanding Stokes
The Stoke (symbol: St) is a unit of kinematic viscosity. The CGS unit of kinematic viscosity equal to exactly 1 cm²/s (= 100 cSt = 10⁻⁴ m²/s).

Frequently Asked Questions
How do I convert Stokes to Centistokes?
The CGS unit of kinematic viscosity equal to exactly 1 cm²/s (= 100 cSt = 10⁻⁴ m²/s). To convert Stokes to Centistokes, multiply by 100. For example, 25 St equals 2500 cSt.
How many Centistokes are in 1 Stoke?
There are 100 Centistokes in 1 Stoke.
How many Stokes are in 1 Centistoke?
There are 0.01 Stokes in 1 Centistoke.
What is the formula for Stoke to Centistoke conversion?
The formula is: multiply by 100. This means 1 St = 100 cSt.
Is a Stoke bigger than a Centistoke?
No. One Stoke is smaller than one Centistoke because 1 St equals 100 cSt, which is greater than 1.
When do you need to convert between Stokes and Centistokes?
A CGS kinematic-viscosity unit equal to exactly 0. Stoke and Centistoke 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.
