What is the equivalent of French 8a in the Yosemite Decimal System?

French 8a is approximately equivalent to 5.13b/c in the Yosemite Decimal System (YDS) and 8+ in the UIAA system. This grade marks the boundary between advanced and elite sport climbing, typically requiring substantial campus board and hangboard training to achieve.

Why do climbing grade systems differ between countries?

Each grading system was developed independently based on local rock types and climbing culture. French grades are open-ended and well-suited to steep limestone pockets; YDS evolved on the friction slabs of Yosemite granite; UIAA used Roman numerals adapted from alpine mountaineering grades.
