Bophara ba kantle (OD): OD ke bophara ba bokaholimo ba kantle ba phaephe ea tšepe e potolohang. OD ea phaephe ea tšepe e potolohang ke boholo ba 'nete ba bokantle ba phaephe. ​​OD e ka fumanoa ka tekanyo ea 'nete, hangata ka limilimithara (mm).
Bophara ba ka Hare (ID): ID ke bophara ba bokaholimo ba ka hare ba phaephe ea tšepe e potolohang. ID ke boholo ba 'nete ba bokahare ba phaephe. ​​ID hangata e baloa ka ho tlosa botenya ba lebota habeli ho OD ka limilimithara (mm) ID = OD-2 x Botenya ba Lebota
