Square Meter per Second (m²/s)
The square metre per second (m²/s) is the SI unit of kinematic viscosity, the dynamic viscosity divided by density. Water at 20 °C is about 1.0 × 10⁻⁶ m²/s.
Symbol: m²/s (ASCII: m2/s)
Quantity: kinematic viscosity (dynamic viscosity divided by density)
SI relation: m²/s is the coherent SI unit of kinematic viscosity.
Derivation: 1 m²/s = 1 m² ÷ 1 s
Exact: yes, by definition
Typical uses
- Reynolds-number and pipe-flow calculations (Re = vD/ν)
- CFD fluid properties
- Diffusivity in heat and mass transfer
