What does 155 Pounds represent?

155 pounds (70.31 kg) is the weight class American boxing and MMA broadcasts call "lightweight," with the 155-lb scale figure converting to 70.31 kg. Outside the US the closest metric divisions are 70 kg in some federations and 71 kg in others, so a fighter weighing in at exactly 155 lbs has to drop another 310 g to make 70 kg or has 690 g of slack against 71 kg.
