1. What is the Calories Burned Equation?

The calories burned equation estimates energy expenditure during physical activity based on the metabolic equivalent (MET) of the activity, body weight, and duration of the activity.

2. How Does the Calculator Work?

The calculator uses the following equation:

Where:

• \( MET \) — Metabolic equivalent of the activity (dimensionless)
• \( Weight \) — Body weight in kilograms (kg)
• \( Time \) — Duration of activity in hours

Explanation: The equation calculates total calories burned by multiplying the intensity of the activity (MET) by body weight and duration.

3. Importance of MET Values

Details: MET values represent the energy cost of activities. One MET is the energy expended at rest (sitting quietly). Higher MET values indicate more intense activities that burn more calories per minute.

4. Using the Calculator

Tips: Enter the MET value for your activity (common values range from 1-12), your weight in kg, and the 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: MET values are published in compendiums of physical activities. Common examples: walking (3-5 METs), running (8-12 METs), cycling (4-10 METs).

Q2: Is this calculation accurate for everyone?
A: It provides an estimate. Individual results may vary based on factors like body composition, fitness level, and exercise efficiency.

Q3: Should I use kg or pounds for weight?
A: The calculator requires weight in kilograms. To convert from pounds, divide by 2.205.

Q4: Can I use minutes instead of hours?
A: Yes, but convert minutes to hours (divide by 60) before entering the value.

Q5: Does this account for afterburn effect?
A: No, this calculation only estimates calories burned during the activity itself, not any additional post-exercise energy expenditure.
