How does the UFC weigh-in work?

-
In title fights , the athlete must respect the exact weight limit of the category;

In non-title fights , there is a tolerance of up to 1 pound (approximately 450 grams) above the limit;
-
If the athlete is ahead, they have up to two hours to try to make up the difference;
-
If you fail to make weight, you may be fined (up to 30% of your purse), lose bonuses , and even have your fight canceled.
