1. What is the Calories Burned Equation?

The calories burned equation estimates energy expenditure during physical activity using MET (metabolic equivalent) values, weight, and duration of activity. 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 (activity intensity)
• \( Weight \) — Body weight in kilograms
• \( Time \) — Duration of activity in hours

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

3. Importance of MET Values

Details: MET values standardize the energy cost of physical activities. One MET equals the energy expenditure while sitting quietly (approximately 1 kcal/kg/hour).

4. Using the Calculator

Tips: Enter MET value (3.0 for moderate walking, 8.0 for running), weight in kg, and time in hours. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What are typical MET values for common activities?
A: Walking (3-5 METs), jogging (7-9 METs), swimming (6-10 METs), cycling (4-12 METs depending on intensity.

Q2: How accurate is this calculation?
A: It provides a reasonable estimate but individual variations in metabolism can affect actual calories burned.

Q3: Should I use kg or pounds for weight?
A: The calculator requires weight in kilograms (1 kg = 2.2 lbs).

Q4: Can I use minutes instead of hours?
A: Convert minutes to hours (30 minutes = 0.5 hours) for accurate results.

Q5: Does this account for afterburn effect?
A: No, this calculates only the calories burned during the activity itself.
