Our Kinematic Viscosity Converter is a specialized tool designed for engineers, fluid dynamicists, and industrial professionals working with fluid flow characteristics. Kinematic viscosity measures a fluid’s resistance to flow under gravity and is crucial for applications ranging from engine lubrication to hydraulic systems.
The converter handles all major kinematic viscosity units including SI (m²/s), CGS (stokes), and imperial measurements, with precise conversions between different systems. It’s particularly valuable for translating between the common centistokes (cSt) used in oil grading and the SI units preferred in scientific calculations.
Convert between all major kinematic viscosity units including m²/s, stokes, centistokes, and imperial measurements.
Includes specialized units like centistokes (cSt) commonly used in oil viscosity grading.
Accurate conversions with up to 8 decimal places for critical engineering applications.
Handles both per-second and per-hour units for different industrial standards.
Kinematic viscosity (ν) is the ratio of dynamic viscosity (μ) to density (ρ): ν = μ/ρ. While dynamic viscosity measures a fluid’s internal resistance to flow, kinematic viscosity incorporates density and relates to how the fluid flows under gravity.
The stokes (St) and centistokes (cSt) are CGS units that provide convenient numbers for typical fluids. 1 cSt = 1 mm²/s, which is about the kinematic viscosity of water at 20°C, making it a practical reference point.
1 St = 1 cm²/s = 0.0001 m²/s. Our converter handles this automatically – 1 m²/s = 10,000 St. The centistokes (cSt) are 1/100 of a stoke: 1 m²/s = 1,000,000 cSt.
SAE 30 oil at 100°C: ~10 cSt, SAE 10W-30 at 100°C: ~10.5 cSt. Gear oils range from ~40-150 cSt. Our converter helps translate these values to other units as needed.
Square inch/hour is sometimes used in US standards for very slow flows (like grease) or in material science for diffusion rates. 1 m²/s = 5,580,010.8 in²/hr.
