Substituting 145 for lbs: 145 × 0.45359237 = 65.7709 kg. The factor 0.45359237 comes from the exact international definition of the Pound relative to the Kilogram, so this answer is precise rather than rounded.

What does 145 Pounds represent?

145 pounds (65.77 kg) is the weight class American MMA broadcasts call "featherweight," with the 145-lb scale figure converting to 65.77 kg in metric. International MMA promotions outside the US instead label the same division as 65 kg, which means a fighter weighing in at exactly 145 lbs is technically over the 65 kg metric cap by 770 g and would have to cut further to compete abroad. This is the conversion that catches American fighters travelling for international shows, and the reason matchmakers, coaches, and weigh-in officials all keep the 0.45359237 multiplier on hand rather than relying on the "divide by 2.2" shortcut.
