What Is This Tool?
This converter facilitates the transformation of dynamic viscosity values from femtopoise (fP), a unit used for extremely small viscosity measurements in SI units, into micropoise (µP), a cgs unit more common in microfluidics and rheology.
How to Use This Tool?
-
Enter the value in femtopoise that you want to convert.
-
Select femtopoise [fP] as the input unit and micropoise [µP] as the output unit.
-
Click the convert button to get the equivalent value in micropoise.
-
Use the result for analysis, comparison, or calibration in your fluid mechanics or rheology work.
Key Features
-
Converts dynamic viscosity values between femtopoise and micropoise units.

-
1000 femtopoise equals 1 × 10⁻⁶ micropoise (1e-6 µP).
Common Use Cases
-
Translating exceptionally low dynamic viscosities in rarefied gas or vacuum system studies.
-
Performing viscosity specifications in molecular or nanoscale fluid simulations.
-
Calibrating low-range viscometers and rheometers in microfluidics or thin-film lubrication research.
-
Comparing historical cgs unit viscosity data with current SI-based measurements.
Tips & Best Practices
-
Ensure that entered values reflect measured or theoretical viscosities within the supported range for accuracy.
-
Interpret conversion results considering the different magnitude scales between femtopoise and micropoise.
-
Use high-precision instruments when measuring viscosities to reduce error during unit translation.
-
Be cautious when comparing data across SI and cgs units because of inherent system differences.
Limitations
-
Conversion involves very small values which can make accurate measurement and representation challenging.
-
Differences between SI and CGS unit conventions require careful analysis when comparing converted data.
-
The tool does not provide scientific explanations beyond unit conversion and does not adjust for experimental uncertainties.
Frequently Asked Questions
-
What does femtopoise measure?
-
Femtopoise is a unit of dynamic viscosity used to express extremely small viscosity values, equal to 10⁻¹⁵ poise or 10⁻¹⁶ pascal-seconds.
-
Why convert femtopoise to micropoise?
-
Converting femtopoise to micropoise allows better comparison, calibration, and usage of small viscosity values within the cgs unit system commonly applied in microfluidics and rheological studies.
-
Is the conversion between femtopoise and micropoise straightforward?
-
Yes, the conversion uses a fixed rate where 1 femtopoise equals 1×10⁻⁹ micropoise, but interpretation requires attention due to the very small magnitudes involved.
