sport.rock-climbing-grade Calculator
Converts between the major rock climbing grade systems — Yosemite Decimal (5.x), French, UIAA, and Fontainebleau — for both sport and trad routes. Essential when reading route descriptions written in a different system than you trained on.
Inputs
Yds Grade
Reference formula or conversion factor shown for context.
Font Grade
Reference formula or conversion factor shown for context.
Crux Angle
Reference formula or conversion factor shown for context.
Route Length
Linear measurement. Ensure consistent units: 1 m = 1,000 mm = 3.281 ft.
Results
YDS grade
Letter or numerical grade indicating quality, creditworthiness, or performance on a defined scale.
Font grade
Letter or numerical grade indicating quality, creditworthiness, or performance on a defined scale.
crux angle
The computed angle in degrees or radians.
route length
The computed linear length.
difficulty index
Mining difficulty — the network target that determines how hard it is to mine a valid block. Auto-adjusts to maintain consistent block times.
