Which kinematic viscosity units are supported?

The converter supports m²/s, cSt, and ft²/s.

What value can I enter?

Enter a non-negative numeric kinematic viscosity value.

How is cSt related to m²/s?

1 cSt equals 1e-6 m²/s, which is also 1 mm²/s.

How is ft²/s converted to m²/s?

1 ft²/s equals 0.09290304 m²/s.

Can I control the displayed precision?

Yes. Set decimal places from 0 to 10; the default is 6.

Kinematic Viscosity Converter (m²/s / cSt / ft²/s)

Convert kinematic viscosity (ν = dynamic viscosity / density) between m²/s (square metres per second, SI base), cSt (centistokes, 1 cSt = 1e-6 m²/s = 1 mm²/s), and ft²/s (square feet per second, 1 = 0.09290304 m²/s). Converts via m²/s to the target unit and also lists the equivalent value in all three units for reference. Reference values: water 20°C ≈ 1.004 cSt, SAE 30 oil ≈ 300–400 cSt at 40°C.

100 cSt → m²/s = 0.0001, ft²/s ≈ 0.001076

100 cSt × 1e-6 = 1e-4 m²/s. ÷ 0.09290304 = 0.001076 ft²/s. Light lubricating oil at 40°C.

1 ft²/s → m²/s = 0.092903, cSt ≈ 92903.04

1 ft²/s × 0.09290304 = 0.09290304 m²/s × 1e6 = 92903.04 cSt. Heavy gear-oil range.
