1. What is Watts Per Kilo?

Watts Per Kilo (W/kg) is a measurement of power-to-weight ratio, commonly used in cycling and other endurance sports to compare athletic performance across different body weights.

2. How Does the Calculator Work?

The calculator uses the simple formula:

Where:

• \( Power \) — Power output in watts (W)
• \( Weight \) — Body weight in kilograms (kg)

Explanation: This ratio indicates how much power an athlete can produce per kilogram of body weight, which is a key performance metric in many sports.

3. Importance of Watts Per Kilo Calculation

Details: The power-to-weight ratio is crucial for assessing athletic performance, especially in sports where athletes need to overcome gravity, such as cycling uphill, running, or climbing.

4. Using the Calculator

Tips: Enter power output in watts and body weight in kilograms. Both values must be positive numbers greater than zero for accurate calculation.

5. Frequently Asked Questions (FAQ)

Q1: Why is watts per kilo important in cycling?
A: It's a key performance metric, especially for climbing, as it shows how efficiently a rider can overcome gravity. Higher W/kg values indicate better climbing ability.

Q2: What are typical W/kg values for different levels of cyclists?
A: Recreational: 2-3 W/kg, Club: 3-4 W/kg, Professional: 5-6+ W/kg (sprinters may have lower W/kg but higher absolute power).

Q3: How can I improve my W/kg ratio?
A: Either increase your power output through training, decrease your body weight through nutrition, or ideally both simultaneously.

Q4: Is W/kg the only important metric in cycling performance?
A: While crucial for climbing, flat terrain and sprinting also depend on absolute power and aerodynamics. Different disciplines require different strengths.

Q5: How often should I measure my W/kg?
A: Regular testing (every 4-8 weeks) can help track training progress, but avoid daily measurements as performance can vary due to fatigue, nutrition, and other factors.
