Four free MMA tools covering weight class lookup, training calorie burn, round timing, and striking statistics. Useful for fighters, coaches, and fans tracking fight metrics.
MMA basics
Mixed Martial Arts combines striking (boxing, Muay Thai, kickboxing) with grappling (wrestling, BJJ, judo) in a unified ruleset. Bouts take place in a cage or ring over 3 rounds of 5 minutes (championship bouts: 5 rounds). Victory comes by KO/TKO, submission, or judges' decision. The UFC uses a 10-point must system for scoring — the winner of each round receives 10 points, the loser 9 (or fewer for knockdowns/dominance).
Weight cutting is a significant part of MMA competition. Fighters cut water weight before the official weigh-in, then rehydrate before fighting. The weight class calculator shows official UFC/promotion boundaries.

What are the UFC weight classes?
UFC men's weight classes (with upper limits): Strawweight 115lb, Flyweight 125lb, Bantamweight 135lb, Featherweight 145lb, Lightweight 155lb, Welterweight 170lb, Middleweight 185lb, Light Heavyweight 205lb, Heavyweight 265lb. Women's classes: Strawweight 115lb, Flyweight 125lb, Bantamweight 135lb, Featherweight 145lb. Catchweight bouts (non-standard weights) are occasionally negotiated.
How is an MMA fight scored?
Most promotions use the 10-point must system. Judges score each round — the winner receives 10 points, the loser 9. A knockdown or dominant round can score 10-8. Three judges score independently; the fighter with the majority of round wins across judges wins a decision. Decisions can be unanimous (all 3 judges agree), split (2-1), or majority (2 judges for one fighter, one scoring a draw).
What striking stats matter most in MMA?
Significant strikes landed per minute (SLpM) and striking accuracy (significant strikes landed ÷ attempted) are the primary striking metrics. Takedown accuracy and takedown defence percentage are the key grappling metrics. Submission attempts per 15 minutes measures ground offensive activity. These statistics are tracked by the UFC's official stats partner for all main card and PPV bouts.
