Is 1 cP equal to 1 mPa s?

Yes. 1 cP equals 0.001 Pa·s, which is 1 mPa·s.

Poise is a CGS dynamic-viscosity unit. 1 P equals 0.1 Pa·s.

Can I convert dynamic to kinematic viscosity here?

No. That requires density through nu equals mu divided by rho.

Technical visual

Parallel plates show dynamic viscosity relating shear stress to a velocity gradient.

Engineering interpretation

Dynamic viscosity relates shear stress to velocity gradient.
For Newtonian fluids, mu is the proportionality between shear stress and shear rate.

What is a dynamic viscosity converter?

Convert dynamic viscosity values used in fluid mechanics, CFD setup, and material data tables.

How to use the dynamic viscosity converter

Enter the dynamic viscosity value. Scientific notation such as 1e6 is supported.
Choose the source unit and target unit.
Select automatic, fixed-decimal, significant-figure, or scientific display formatting.
Review the primary result, base-unit normalization, formula substitution, and all-unit comparison table.
Copy the result, copy a share link with safe URL state, or print the calculation summary when needed.

Supported dynamic viscosity units

Supported units include Pa·s, mPa·s, µPa·s, P, cP, kg/(m·s), g/(cm·s), lbm/(ft·s), lbm/(ft·h), and lbf·s/ft^2.

Dynamic Viscosity conversion formula

Dynamic viscosity normalizes to Pa·s. Kinematic viscosity requires density and is handled by a separate converter.

Worked examples

1 cP to Pa·s

Method: mu_base = mu_input x factor_from; mu_output = mu_base / factor_to.

Result: 1.00000e+0 cP = 1.00000e-3 Pa·s

1 P to Pa·s

Method: mu_base = mu_input x factor_from; mu_output = mu_base / factor_to.

Result: 1 P = 0.100000 Pa·s

1 lbm/(ft·s) to Pa·s

Method: mu_base = mu_input x factor_from; mu_output = mu_base / factor_to.

Result: 1 lbm/(ft·s) = 1.488164 Pa·s

For engineering, simulation, and research work

The Dynamic Viscosity Converter normalizes to Pa·s and explains shear stress, velocity gradient, cP, and why density is needed for kinematic viscosity.

Common mistakes

Confusing cP with cSt.
Ignoring temperature dependence.
Converting directly between dynamic and kinematic viscosity without density.

Limitations

This converter does not infer density or fluid model.
Non-Newtonian fluids require shear-rate-specific data.

Technical notes

Negative dynamic viscosity is not valid for ordinary physical-property conversion.
This converter does not infer density or fluid model.
Non-Newtonian fluids require shear-rate-specific data.
