* The raso was a retail measure used, for example, for cloth, and was not divided into punti, atomi, etc, but rather into fractional parts: halves, thirds, fourths, sixths, eighths and sixteenths.

As the absence of integral multipliers for the piede legale demonstrates, it was a late, non-local addition.

Special units of volume

Cubic units were formed in the usual way from units of length, but the way they were subdivided was unusual. For example, a piede cubo would consist of 1728 once cubo (at 12 once to the piede, = 12 × 12 × 12). However, the piede cubo was itself subdivided into 12 once di piede cubo, each of which contained 144 once cubo. Similiarly the once di piede cubo would be subdivided into 12 punti, and so on.

Name Nature Value before 1818,

Value after 1818,

trabucco camerale da muro A quantity of masonry work, a base of 1 square trabucco and a height of 10 once, = 6 × 6 × 10/12 = 30 cubic piede. 4.068342 4.083499
tesa for hay and straw; 125 piedi manuali cubi, which is = 5 piedi di tesa cuba. Like the manuali cubi, the piedi di tesa cuba is divided into 8 once.    
tesa da legna for firewood; 1 square tesa as its base and 4 piedi manuali in height. 4.018116 4.033086
tesa da pozzi for wells; = 45 piedi manuali cubi 1.808152 1.814889
carro di pietra for rock; = 2592 cubic once 0.203417 0.204175
