1. What is the Calorie Burn Equation?

The calorie burn equation estimates calories burned during physical activity based on MET (Metabolic Equivalent of Task) value, body weight, and time spent exercising. It provides a standardized way to compare energy expenditure across different activities.

2. How Does the Calculator Work?

The calculator uses the calorie burn equation:

Where:

• \( MET \) — Metabolic Equivalent of Task (3.5 for walking)
• \( weight \) — Body weight in kilograms
• \( time \) — Duration of activity in hours

Explanation: The equation multiplies the intensity of the activity (MET) by your body weight and the time spent to estimate total energy expenditure.

3. Importance of MET Values

Details: MET values represent the energy cost of activities. One MET is defined as the energy it takes to sit quietly (about 1 kcal per kg per hour). Walking typically has a MET value of 3.5, meaning it burns 3.5 times more calories than sitting.

4. Using the Calculator

Tips: Enter your weight in kg, time in hours (use 0.5 for 30 minutes), and the MET value (default is 3.5 for walking). All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What is a typical MET value for walking?
A: Walking at 3-4 mph typically has a MET value of 3.5. Faster walking or walking uphill increases the MET value.

Q2: How accurate is this calculation?
A: It provides a reasonable estimate but individual variations in metabolism, terrain, and walking efficiency affect actual calorie burn.

Q3: Should I use kg or pounds?
A: The calculator uses kg. To convert pounds to kg, divide by 2.205.

Q4: Can I use this for other activities?
A: Yes, by changing the MET value. Running (6-8 METs), cycling (4-8 METs), etc.

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