Questions fréquemment posées
What is the most widely used climbing grading system?
The Yosemite Decimal System (YDS) is dominant in North America, while the French system is standard in Europe and most of the world. UIAA is common in Central and Eastern Europe.
Are grade conversions exact?
No. Grade conversion is approximate because different systems have different granularity and subjective inputs from different climbing communities. Use conversions as estimates only.
What is the V-scale used for?
The V-scale (Hueco scale) is specifically for bouldering — short, powerful routes without ropes. V0 is entry-level bouldering; elite climbers work on V15-V17.
