How This Converter Works
This dynamic viscosity converter uses linear scaling — converting between units using multiplication factors based on the viscosity relationship.
Step 1: Convert input value using the "From" unit's factor
Step 2: Convert to the "To" unit using the target unit's factor

Dynamic Viscosity Converter: Convert Pa·s, Poise and Centipoise
Viscosity describes how strongly a fluid resists deformation and flow. It is an important property in lubrication, chemical processing, fluid mechanics, manufacturing, and many other engineering applications.
The problem is that viscosity appears in several unit systems.
A specification might use Pa·s.
Another might use poise or centipoise.
A Dynamic Viscosity Converter helps you convert between these units quickly.
The CalculatorKits tool supports more than 25 dynamic viscosity units, including Pa·s, poise, centipoise, pound force second units, and kgf·s/m².

What Is Dynamic Viscosity?
Dynamic viscosity measures a fluid’s resistance to deformation under shear.
Its SI unit is:
pascal second, Pa·s
NIST identifies the pascal second as the SI unit for dynamic viscosity.
Common alternative units include:
- Pa·s
- mPa·s
- Poise
- Centipoise
- lb/(ft·s)
How to Use the Dynamic Viscosity Converter
1. Enter the Viscosity
Enter your numerical value.
2. Choose the From Unit
Select the unit used by your source.
3. Choose the To Unit
Select the desired target unit.
4. Convert
The result appears immediately.
5. Review the Calculation
The CalculatorKits page shows the conversion factor used.
Pa·s to Poise
One of the most common conversions is:
1 Pa·s = 10 P
CalculatorKits uses this relationship as its example.
NIST also gives the relationship between poise and pascal second as:
1 P = 0.1 Pa·s
Centipoise and Dynamic Viscosity
Centipoise is widely encountered in fluid specifications.
For example:
1 cP = 1 mPa·s
This makes centipoise convenient for relatively low viscosity fluids.
You may encounter cP when reading specifications for oils, coatings, chemicals, and other fluids.
Dynamic vs Kinematic Viscosity
This distinction is extremely important.
Dynamic viscosity is commonly represented by μ.
Kinematic viscosity is commonly represented by ν.
Kinematic viscosity relates dynamic viscosity to density:
ν = μ ÷ ρ
Therefore, you cannot generally convert dynamic viscosity to kinematic viscosity using only a unit conversion factor.
You need density.
If you already have a kinematic viscosity value, use the Kinematic Viscosity Converter.
Where Is Dynamic Viscosity Used?
A dynamic viscosity unit converter can be useful in:
- Lubrication
- Chemical processing
- Fluid mechanics
- Petroleum engineering
- Automotive engineering
- Food processing
- Paint and coatings
- Laboratory work
- Pump and pipe calculations
Why Use a Dynamic Viscosity Converter?
Viscosity values can differ greatly in numerical scale.
A value in Pa·s may look completely different from the same value in cP or poise.
The converter lets you change the unit without repeatedly checking tables.
CalculatorKits uses linear scaling and the general relationship:
Result = Input × From Factor ÷ To Factor
Limitations
The calculator converts viscosity units.
It does not determine viscosity from temperature, pressure, fluid composition, or laboratory measurements.
Viscosity can also depend strongly on temperature and, for some fluids, shear rate.
Therefore, converting a number does not guarantee that the number represents the fluid under your actual operating conditions.
Frequently Asked Questions
What is the SI unit of dynamic viscosity?
Pascal second, Pa·s.
What is 1 Pa·s in poise?
1 Pa·s equals 10 poise.
What is centipoise?
Centipoise is one hundredth of a poise and is commonly used for fluid viscosity.
Is dynamic viscosity the same as kinematic viscosity?
No. Kinematic viscosity also involves fluid density.
Can this calculator measure viscosity?
No. It converts existing viscosity values.
