The second dozenal power of the ⚀lengthel, the ⚀biqua·lengthel (abbreviated ⚀b↑lgℓ) is one dozen ⚀hand·lengths, or one gross ⚀morsel·lengths. This is the distance traversed in 1 ⚀lull (4.2z seconds) when moving at 1 ⚀velocitel. In SI units, this comes out to exactly 118.11d centimeters, very close to a dozen decimeters. In USC units, it comes out to exactly 46.5d (|3ᘔ.6z) inches inches. This makes a good approximation for the English ell, an old unit of cloth measure, which was 45d (|39z) inches inches. Consequently, Primel proposes to colloquialize this the ⚀ell·length (or ⚀ulnaral·length).

(The English word “ell” appears to be derived from the Latin ulna, “forearm”, which would actually suggest a length half as large. However, clothiers evidently measured out cloth stretched across both forearms. Since the Latin genitive plural for ulna is ulnarum, “of the forearms,” Primel derives the adjective ulnaral from that.)
