Ka soo qaad inaan sameeyo qadaadiic been abuur ah oo la dhaho "yarns" laba nooc oo qadaadiic ah: "super yarn" oo ah 10 yarn iyo "mini yarn" oo ah 0.5 yarn. Imisa lacag ah ayaan haystaa hadii aan haysto labo xarig oo waaweyn iyo sadex xarig oo yaryar?
Marka la eego in xargaha super-yarn uu u dhigmo 10 xargaha yaryar, xargaha mini-yarn uu u dhigmo 0.5 xargaha yaryar, haddii aad leedahay 2 xargaha super-yarn iyo 3 xargaha mini-yarn waxaad leedahay 21.5 xargaha yaryar.
