Climbing Grade Converter

Convert between French, YDS, UIAA, and V-scale climbing grades

Rock climbing grades measure route difficulty across different systems. French/Fontainebleau is standard in Europe, YDS in the US, and V-scale for bouldering.

💡

Tip: Grades are subjective and vary by crag, region, and style. Climb the rock, not the grade.

Fun Fact

The world’s hardest rated route (9c) was first completed by Adam Ondra in 2017 at Flatanger Cave, Norway.
