What Is This Tool?
This converter helps you translate dynamic viscosity measurements between the metric unit millinewton second per square meter (mN·s/m²) and the imperial engineering unit pound per foot per hour [lb/(ft·h)]. It is designed for applications requiring conversion between these units in various scientific, engineering, and industrial contexts.

Tips & Best Practices
-
Ensure that you are converting dynamic viscosity, as this tool does not apply to kinematic viscosity
-
Double-check unit selections to avoid mixing metric and imperial systems incorrectly
-
Use the provided conversion factor directly to maintain accuracy
-
Interpret results carefully considering the time unit difference between seconds and hours
-
Apply the tool in engineering, scientific, or industrial workflows requiring consistent unit translation
Limitations
-
Conversion only applies to dynamic (absolute) viscosity, not other viscosity types
-
The difference in time base (second vs. hour) and unit systems (metric vs. imperial) requires cautious interpretation
-
Rounding conversion factors may introduce minor inaccuracies
-
It does not provide viscosity definitions beyond dynamic measurements
Frequently Asked Questions
-
What type of viscosity does this converter apply to?
-
This conversion tool is designed for dynamic (absolute) viscosity measurements only.
-
Why can’t I use this converter for kinematic viscosity?
-
Because kinematic viscosity has different units and physical meaning, this tool only converts dynamic viscosity units.
-
How does the time unit difference affect the conversion?
-
This converter accounts for the fact that metric units use seconds while imperial units use hours, so careful handling is needed to avoid errors.
Key Terminology
-
Millinewton second per square meter (mN·s/m²)
-
A metric unit of dynamic viscosity equal to 1×10⁻³ pascal-second, quantifying fluid resistance to shear flow.
-
Pound per foot per hour [lb/(ft·h)]
-
An imperial unit expressing dynamic viscosity relating shear stress to velocity gradient, commonly used in US-customary engineering.
-
Dynamic viscosity
-
A physical property indicating a fluid’s internal resistance to shear or flow under applied stress.
