Queste tabelle permettono di operare la conversione dei valori di rigidezza delle molle, nelle unità di misura più usate sulle autovetture da competizione. Il loro uso è molto semplice: dato il valore da convertire (es. 500 Lb/in) si va sulla tabella relativa (in questo caso quella delle Lb/in) e si ha immediatamente il controvalore nell'unità di misura desiderata ( 88,18 N/mm o 11,34%).
