Learn how to use the Cycling watts per kilogram calculator and understand your performance metrics

How to use the calculator

  1. Enter your cycling power output in watts (W) from a power meter or estimated from your cycling data
  2. Input your body weight in kilograms (kg)
  3. Provide your age and select your gender
  4. Click the "Calculate" button to see your watts per kilogram ratio and performance classification

Understanding the results

The watts per kilogram (W/kg) ratio is a critical metric in cycling performance that represents your power relative to your body weight. It's one of the best indicators of cycling ability and efficiency.

Performance classification

  • Beginner: W/kg < 2.5
  • Intermediate: 2.5 ≤ W/kg < 3.0
  • Advanced: 3.0 ≤ W/kg < 3.5
  • Elite: W/kg ≥ 3.5

What does W/kg tell you?

A higher W/kg ratio indicates a more powerful cyclist relative to their size. This metric is particularly useful for comparing cyclists of different body weights and for tracking your own progress over time.

Important notes

Remember that W/kg is just one aspect of cycling performance. Other factors like endurance, technique, and equipment also play important roles. Consistently training and improving your W/kg ratio will lead to better cycling performance across all disciplines.
