Sobre sistemas de unidades

Si existe el año-luz... por qué no el segundo-barba. Que igualmente es una unidad de distancia (la distancia que crece la barba de un físico promedio en un segundo). Google sabe convertirla en otras unidades, tomando como factor de conversión 1 segundo-barba = 5 nanómetros.

En belleza, una "(H)elena de Troya".
Helen of Troy (from the Iliad) is widely known as "the face that launched a thousand ships." Thus, 1 millihelen is the amount of beauty needed to launch a single ship.

Negative values have also been observed—these, of course, are measured by the number of ships sunk or the number of clocks stopped. An alternative interpretation of 1 negative Helen is the amount of negative beauty (i.e. ugliness) that can launch one thousand ships the other way.

Since the original quotation was "Was this the face that launch'd a thousand ships and burnt the topless towers of Ilium", a more accurate definition of the millihelen might be the amount of beauty required to launch a single ship and ignite a wastebasket.

David Lance Goines has written a humorous article describing various Helen-units. It has a chart with the fire-lighting and ship-launching capability for different powers of "Helens". For example, a Picohelen (ph) (10^-12 helens) indicates the amount of beauty that can "Barbecue a couple of Steaks & Toss an Inner Tube Into the Pool".

Lectura entretenida jeje.
