Frequently Asked Questions
-
What units does this converter work with?
-
It converts dynamic viscosity units from poundal second per square foot (FPS system) to slug per foot per second (US customary system).
-
Why convert between these two units?
-
The conversion helps translate older FPS-based viscosity data to US customary units commonly used in fluid dynamics and engineering calculations.
-
Is this conversion suitable for comparing to SI units?
-
Yes, although care should be taken as these Imperial units differ from SI units, and additional conversion may be required.
