Frequently Asked Questions
-
What does femtostokes measure?
-
Femtostokes measure kinematic viscosity on an extremely small scale, representing momentum diffusivity in fluids, derived from stokes and CGS units.
-
Why convert femtostokes to square foot per second?
-
Converting to square foot per second allows using kinematic viscosity values in US customary units commonly applied in engineering and fluid mechanics.
-
Can this conversion be used for macro-scale viscosities?
-
This conversion is best suited for very small viscosities; larger viscosities may require other unit conversions appropriate to their scale.
