Marimea unui inel se poate lua tinand cont de mai multe atribute, insa doua dintre acestea sunt mai des folosite:
diametrul si circumferinta inelului.
Intre acestea exista o relatie directa, si anume: Circumferinta = Diametrul * PI (3.141592)
Silver4You foloseste pentru masurarea inelelor diametrul acestora. Am calculat, pentru tine, valorile circumferintei pentru
gama de diametre folosite in mod curent de noi, astfel:
