The ⚀unqua·lengthel, or ⚀hand·length
The first positive dozenal power of the ⚀lengthel, the ⚀unqua·lengthel (abbreviated ⚀u↑lgℓ) is a dozen ⚀morsel·lengths. This is the distance traversed in a ⚀twinkling (a little over a third of a second) when moving at 1 ⚀velocitel. In SI units, this comes out to exactly 9.8425d centimeters, and therefore is very close to 1 decimeter. In USC units, it comes out to exactly 31/8d|27/8z inches (3.875d|3.ᘔ6z inches). This makes a good approximation for the USC hand unit, which is 4 USC inches. As a consequence, a proposed colloquial name for this is the ⚀hand·length (or ⚀manual·length).
