Thewelterweight division inmixed martial arts contains differentweight classes:
Many other sports that use thewelterweight class, such asboxing,kickboxing, andMuay Thai, define it as below about 147 lb (67 kg). The MMA welterweight class is therefore significantly heavier than the welterweight class of these other sports.For the sake of uniformity, manyAmerican mixed martial arts websites refer to competitors between 156 and 170 lb (71 and 77 kg) as welterweights. This encompasses the Shooto middleweight division (167 lb / 76 kg).
The welterweight limit, as defined by theNevada State Athletic Commission[1] and theAssociation of Boxing Commissions[2] is 170 lb (77kg).
