1. What is the Calories Burned Equation?

The calories burned equation estimates energy expenditure during physical activity using MET (Metabolic Equivalent of Task) values, weight, and exercise duration. It provides a practical way to quantify exercise intensity and energy expenditure.

2. How Does the Calculator Work?

The calculator uses the calories burned equation:

Where:

• \( MET \) — Metabolic Equivalent of Task (unitless)
• \( Weight \) — Body weight in kilograms
• \( Time \) — Exercise duration in hours

Explanation: The equation multiplies the MET value (representing exercise intensity) by body weight and exercise duration to estimate total calories burned.

3. Importance of MET Values

Details: MET values standardize exercise intensity. 1 MET = resting metabolic rate (~1 kcal/kg/hour). Higher MET values indicate more intense activities.

4. Using the Calculator

Tips: Enter MET value (common activities: walking=3.5, running=8, cycling=6-8), weight in kg, and duration in hours. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: Where can I find MET values for different activities?
A: The Compendium of Physical Activities provides comprehensive MET values for hundreds of activities.

Q2: How accurate is this calculation?
A: It provides reasonable estimates for most people, but individual variations in metabolism can affect actual calories burned.

Q3: Should I use kg or pounds for weight?
A: The equation requires weight in kilograms. To convert pounds to kg: weight in kg = weight in lbs / 2.205.

Q4: Can I use minutes instead of hours?
A: Yes, but convert minutes to hours (e.g., 30 minutes = 0.5 hours) for accurate results.

Q5: Does this account for afterburn effect?
A: No, this calculates only calories burned during the activity. Some intense exercises continue burning calories afterward.
