Climbing Grade Converter

By Blue Fusion Technologies, LLC

This app is only available on the App Store for iOS devices.


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 13 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.

Help support a fellow climber!
