Formula
Formula
St = m²/s × 10000
Multiply any value in square metres per second by 10000 to obtain the value in stokes.
Worked example
Convert 1 m²/s to St.
- 01Start with 1 m²/s.
- 02Multiply by the conversion factor: 1 × 10000 = 10000 St.
Result1 m²/s = 10000 St

FAQ
What is the conversion factor from m²/s to St?
1 m²/s equals 10000 St. To convert, multiply the value in square metres per second by 10000.
How do I convert 1 m²/s to St?
1 m²/s = 10000 St. For any value, multiply by 10000.
How do I convert St back to m²/s?
Divide by the same factor — or equivalently, multiply by 0.0001. So 1 St = 0.0001 m²/s.
When would I need to convert square metre per second to stoke?
Kinematic viscosity conversions between m²/s and St arise in hydraulic fluid selection, lubricant grading (ISO VG), pipe flow Reynolds number calculations, and fuel-oil specification. Kinematic viscosity equals dynamic viscosity divided by fluid density and cannot be directly compared to dynamic viscosity without that context.
Is the conversion exact?
The factor shown is precise to at least 7 significant figures. For most process-engineering work this is far better than instrument accuracy. For metrology or trade applications, refer to the relevant national standard (NIST, BIPM, ISO 80000).
