The V-scale is an open-ended scale that starts at V0 (although a slightly easier "VB" has been used for beginners), and increases in single-digit steps (i.e. V5, V6, V7), and was at V17 in 2023 with Burden of Dreams. The V-scale doesn't consider risk and is purely focused on the technical difficulty of the movements. [2]
The hardest boulder solved was at the boulder grade of V17 (9A) for men and V15/V16 (8C/8C+) for women. The hardest multi-pitch (or big wall) redpoint was at the grade of 9a+ (5.15a). The hardest single-pitch free solo was at the grade of 8c (5.14b), and the hardest multi-pitch (or big wall) free solo was at 7c+ (5.13a).
Bouldering problems are assigned numerical difficulty ratings by route-setters and climbers. The two most widely used rating systems are the V-scale and the Fontainebleau system. [11] The V-scale, which originated in the United States, is an open-ended rating system with higher numbers indicating a higher degree of difficulty.

Roughness length is a parameter of some vertical wind profile equations that model the horizontal mean wind speed near the ground. In the log wind profile, it is equivalent to the height at which the wind speed theoretically becomes zero in the absence of wind-slowing obstacles and under neutral conditions. In reality, the wind at this height ...
