What is a decistoke (dSt)?
-
A decistoke is a unit of kinematic viscosity equal to one tenth of a stokes (0.1 St), representing 1.0×10⁻⁵ m²/s, used mainly in CGS-based measurements.
-
Why convert decistokes to square inch per second?
-
Converting from decistokes to square inch per second allows users to switch between metric CGS units and imperial/US customary units for compatibility in engineering and reporting.
-
What industries use this conversion?
-
Industries such as lubrication engineering, hydraulic system design, petroleum refining, and fluid dynamics modeling commonly use this conversion.
