About the viscosity — kinematic converter

Convert kinematic viscosity between m²/s (SI), stokes (St), centistokes (cSt), and ft²/s. Kinematic viscosity is dynamic viscosity divided by density and predominates in lubricant specifications — SAE and ISO viscosity grades use cSt at 40 °C and 100 °C.

Frequently asked questions

  • How many m²/s is 1 centistoke?

    One cSt equals exactly 1 × 10⁻⁶ m²/s, or 1 mm²/s.

  • What is the kinematic viscosity of water?

    About 1.0 cSt at 20 °C.

  • Why are oils rated in cSt?

    Oil grade specifications (ISO VG, SAE) target lubrication performance, which depends on flow under gravity — directly captured by kinematic viscosity.
