Grade Conversion Table

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. For example, during October 1998 Chris Jones climbed a number of E7s, and when asked what E7 meant, his reply was "24/25 and certain death, 26/27 and broken bones, 28/29 and safe."
