Is 1 cSt equal to 1 mm2/s?

Yes. 1 cSt equals 1 mm^2/s and 1e-6 m^2/s.

1 St equals 1 cm^2/s, which is 100 cSt.

How is kinematic viscosity related to dynamic viscosity?

Kinematic viscosity nu equals dynamic viscosity mu divided by density rho.

Technical visual

Kinematic viscosity links dynamic viscosity and density through nu equals mu divided by rho.

Engineering interpretation

Kinematic viscosity is nu = mu / rho.
Centistokes and mm^2/s are numerically equal.

What is a kinematic viscosity converter?

Convert kinematic viscosity units used in fluid mechanics and CFD without inferring density or dynamic viscosity.

How to use the kinematic viscosity converter

Enter the kinematic 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 kinematic viscosity units

Supported units include m^2/s, mm^2/s, cm^2/s, St, cSt, ft^2/s, and in^2/s.

Kinematic Viscosity conversion formula

Kinematic viscosity normalizes to m^2/s. Dynamic-to-kinematic conversion requires density and is not inferred here.

1 St to cSt

Method: nu_base = nu_input x factor_from; nu_output = nu_base / factor_to.

Result: 1 St = 100 cSt

1 ft^2/s to m^2/s

Method: nu_base = nu_input x factor_from; nu_output = nu_base / factor_to.

Result: 1 ft^2/s = 0.09290304 m^2/s

For engineering, simulation, and research work

The Kinematic Viscosity Converter normalizes to m^2/s and explains nu equals dynamic viscosity divided by density.

Common mistakes

Confusing cSt with cP.
Assuming density is unnecessary for dynamic/kinematic conversion.
Ignoring temperature dependence.

Limitations

This converter does not infer fluid density.
It does not model temperature-dependent viscosity curves.

Technical notes

Negative kinematic viscosity is not valid for ordinary physical-property conversion.
This converter does not infer fluid density.
It does not model temperature-dependent viscosity curves.
