1. What is the Calorie Burn Formula?

The calorie burn formula estimates calories burned during physical activity based on duration, intensity (MET value), and body weight. It provides a practical way to estimate energy expenditure during exercise.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( Time \) — Duration of activity in hours
• \( MET \) — Metabolic Equivalent of Task (activity intensity)
• \( Weight \) — Body weight in kilograms

Explanation: The formula accounts for the relationship between activity duration, intensity, and body weight in determining energy expenditure.

3. Importance of MET Values

Details: MET values represent the intensity of physical activities. Common running MET values range from 6 (light jogging) to 23 (sprinting at 20.9 km/h).

4. Using the Calculator

Tips: Enter time in hours, select appropriate MET value for your running intensity, and your weight in kg. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What are typical MET values for running?
A: MET values vary by speed: 6 for 6.4 km/h, 8 for 8 km/h, 9.8 for 9.7 km/h, 11 for 11.3 km/h, etc.

Q2: How accurate is this calculation?
A: It provides a reasonable estimate but individual factors like fitness level and body composition can affect actual calorie burn.

Q3: Should I use my current weight or goal weight?
A: Always use your current weight for most accurate calculations.

Q4: Does this account for afterburn effect?
A: No, this calculates only calories burned during the activity. Higher intensity exercise may increase post-exercise calorie burn.

Q5: Can I use this for other activities?
A: Yes, by using the appropriate MET value for any activity (walking, cycling, swimming, etc.).
