What is Watts Per Kilogram (W/kg)?

Power output relative to body weight, the gold standard for comparing climbing ability.

Deep Dive

A ratio that expresses your power output relative to your body mass. While absolute power (Watts) matters most on flat terrain and descents, W/kg represents your ability to fight gravity. It is the primary determinant of speed on steep gradients.

Formula
W/kg = Power (Watts) / Body Weight (kg)

Why It Matters

It allows for fair comparison between riders of different sizes. To climb faster, you can either increase your power or decrease your weight.
