Viscosity Calculator

Convert between dynamic and kinematic viscosity units, and relate the two through fluid density.

Choose a calculation mode

Mode

Dynamic Viscosity, μ

Unit

Fluid Density, ρ (kg/m³)

Water ≈ 1000 kg/m³

Calculated viscosity value

Kinematic Viscosity, ν

0.00000

Viscosity relations and unit definitions

ν = μ/ρ: kinematic = dynamic / density

Reynolds: Re = ρ·v·L/μ = v·L/ν

1 Pa·s: = 1000 cP = 10 P

1 cP: = 0.001 Pa·s

1 m²/s: = 1×10⁶ cSt

1 cSt: = 1 mm²/s
