Climbing Grade Converter Free

By Blue Fusion Technologies, LLC

Open iTunes to buy and download apps.


Climbing Grade Converter is a simple tool used to help rock climbers understand the different grading systems used around the world. Currently the app converts between 16 different climbing grading systems including bouldering systems.

Keep in mind that climbing grades are subjective and are agreed upon by a consensus. Also, there is disagreement on how certain systems convert to other systems since different systems take into account different factors (i.e. hardest move, overall difficulty, etc). I've attempted to compile all data I could find to create the most comprehensive conversion tool I could.

Grading Systems Included:
Yosemite (YDS)
British Adjectival
UIAA (Central Europe)
Ewbank (Australia)
South Africa
Ogawayama (Bouldering)
Fontainebleau (Bouldering)
Hueco (Bouldering)
Toyota (Bouldering)

Note: Grading system selection list is only available with the full version in-app upgrade. Otherwise the app is limited to only the Yosemite Decimal System (USA).
