The centistoke is the most common practical unit for kinematic viscosity in industry, equal to 1 mm²/s.
Defined as one hundredth of the CGS stokes unit, it became the standard practical measurement in the petroleum and lubricant industry.
Measurement system: CGS system (non-SI, common practical unit). SI equivalent: 1 cSt = 1 mm²/s = 0.000001 m²/s.
