Converting units of kinematic viscosity, such as attostokes (aSt) to terastokes (TSt), can seem daunting—especially when dealing with extreme values like 620.4 aSt to TSt. But don’t worry! This guide simplifies the process, ensuring no math stress while delivering accurate results.
Whether you’re an engineer, scientist, or student, understanding this conversion is essential for fluid dynamics, lubrication studies, and industrial applications. Let’s break it down step by step.
Understanding Stokes and Its Units
The stokes (St) is a unit of kinematic viscosity, commonly used in fluid mechanics. Since kinematic viscosity values can vary widely, metric prefixes help express them efficiently:
| Unit | Symbol | Equivalent in Stokes (St) |
|---|---|---|
| Attostokes | aSt | 10⁻¹⁸ St |
| Femtostokes | fSt | 10⁻¹⁵ St |
| Picostokes | pSt | 10⁻¹² St |
| Nanostokes | nSt | 10⁻⁹ St |
| Microstokes | µSt | 10⁻⁶ St |
| Millistokes | mSt | 10⁻³ St |
| Centistokes | cSt | 10⁻² St |
| Stokes | St | 1 St |
| Kilostokes | kSt | 10³ St |
| Megastokes | MSt | 10⁶ St |
| Gigastokes | GSt | 10⁹ St |
| Terastokes | TSt | 10¹² St |
Our goal is to convert 620.4 attostokes (aSt) to terastokes (TSt).
Step-by-Step Conversion: 620.4 aSt to TSt
Step 1: Understand the Relationship Between aSt and TSt
- 1 attostoke (aSt) = 10⁻¹⁸ stokes (St)
- 1 terastoke (TSt) = 10¹² stokes (St)
To convert aSt → TSt, we need to bridge the gap between these two units.
Step 2: Convert Attostokes to Stokes
First, express 620.4 aSt in stokes (St):620.4 aSt=620.4×10−18 St620.4aSt=620.4×10−18St
Step 3: Convert Stokes to Terastokes
Now, convert Stokes (St) to Terastokes (TSt):1 TSt=1012 St1TSt=1012St
So, to find the equivalent in TSt, divide by 10121012:620.4×10−18 St=620.4×10−181012 TSt620.4×10−18St=1012620.4×10−18TSt=620.4×10−30 TSt=620.4×10−30TSt
Final Conversion Result
620.4 aSt=6.204×10−28 TSt620.4aSt=6.204×10−28TSt
Why This Conversion Matters
Understanding attostokes to terastokes conversions is crucial in:
✅ Nanotechnology & Microfluidics – Working with extremely low viscosity fluids.

Common Mistakes to Avoid
❌ Misplacing the Decimal Point – Ensure correct exponent handling.
❌ Ignoring Unit Prefixes – Confusing atto (10⁻¹⁸) with tera (10¹²) leads to errors.
❌ Skipping Intermediate Steps – Always convert to base (Stokes) first for accuracy.
