While many might be used to the 18 divisions that boxing has to offer, the MMA weight divisions are slightly different and can be the cause of some confusion. The main reason for this confusion is often because the upper weight limit for each division can vary wildly what each division's limit in boxing is. As UFC continues to grow, a through understanding of the divisions and their titles is a necessity.
