Kinematic Viscosity Calculator

Find kinematic viscosity from dynamic viscosity and density.

Calculated Output

Kinematic viscosity (m²/s) 0

Kinematic viscosity (cSt) 14.776

Formula: ν = μ ÷ ρ

Step-by-Step Breakdown

1. Values used:

2. Dynamic viscosity = 0 Pa·s

3. Density = 1.225 kg/m³

5. Kinematic viscosity = Dynamic viscosity / Density = 0 / 1.225 = 0m²/s

6. Kinematic viscosity = 14.776cSt

The math behind it

ν = μ ÷ ρ. It appears in the Reynolds number and governs momentum diffusion.

Air (μ 1.81×10⁻⁵, ρ 1.225) → about 1.48 × 10⁻⁵ m²/s (14.8 cSt).

Dynamic vs kinematic?

Dynamic is resistance to flow; kinematic also accounts for the fluid's density.
