Disclaimer
All conversions are approximate as there is no official standard for making conversions. Cross-discipline grade comparison is inherently imprecise due to differing physical and technical demands. Climbing grades are subjective and difficulty can vary from indoor to outdoor, gym to gym, and crag to crag.
