Grade Conversion
Note: Grading is an inexact art, even when only a single grading system is being considered. Conversions between different grading systems are therefore likely to be innaccurate (in some cases grossly!).

* UK subjective gradings don't necessarily translate as shown above (particularly in the higher E grades), since this system measures the subjective difficulty of a climb, not the technical difficulty.
