Notes

IBJJF Gi weigh-ins include the gi (~2 kg / 4.5 lbs). No-Gi is body weight only.
ADCC uses kg only (5 men's / 2 women's classes). Biennial worlds, most prestigious no-gi event.
WNO (Who's Number One) uses lbs. Pro no-gi series by FloGrappling.
Gi sizes vary between manufacturers — always cross-reference brand charts.
IBJJF kg is authoritative; lbs values are conversions rounded to common published figures.
