GRADE CONVERTER

About Climbing Grades

Grade conversions are approximate. Different systems were developed independently and don't always map 1:1. The same grade can feel different depending on rock type, style, and conditions. Use this as a rough guide, not gospel.

• YDS — Yosemite Decimal System, standard in North America.
