Convert dynamic viscosity (Pa·s, poise, cP) and kinematic viscosity (m²/s, stokes, cSt). Pick one family.
result = value × (from→Pa·s) ÷ (to→Pa·s); kinematic via m²/s
It converts convert dynamic viscosity (pa·s, poise, cp) and kinematic viscosity (m²/s, stokes, cst). pick one family by first normalising your value to the SI base unit (pascal-second) and then scaling to your chosen target unit. This hub-and-spoke approach guarantees every unit pair is internally consistent.
1 Pa·s to cP: 1 × 1 = 1 Pa·s, then ÷ 0.001 = 1000 cP.
Dynamic viscosity (Pa·s, poise) is raw resistance to flow; kinematic viscosity (m²/s, stokes) is dynamic viscosity divided by density. They describe different things, so convert within one family only — never mix Pa·s with m²/s.

Conversions are exact ratios where the units are defined exactly (most SI and imperial units) and best-available constants otherwise. Extremely large or small magnitudes are shown in general (g) format; round-tripping through the base unit may introduce tiny floating-point differences in the final decimal places.
