1. What is Kcal Expenditure?

Kcal expenditure represents the number of calories burned during physical activity. It's calculated using the Metabolic Equivalent of Task (MET) value, which measures the energy cost of activities.

2. How Does the Calculator Work?

The calculator uses the kcal expenditure equation:

Where:

• \( MET \) — Metabolic Equivalent of Task (intensity of activity)
• \( weight_{kg} \) — Body weight in kilograms
• \( time_h \) — Duration of activity in hours

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

3. Importance of Kcal Calculation

Details: Calculating kcal expenditure helps in weight management, exercise planning, and understanding energy balance. It's essential for creating effective fitness and nutrition programs.

4. Using the Calculator

Tips: Enter the MET value for your activity (common values range from 1 for sitting to 10+ for intense exercise), your weight in kg, and the duration 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), running (7-12), cycling (4-10), swimming (5-10). Sedentary activities are typically 1-2 METs.

Q2: How accurate is this calculation?
A: It provides a good estimate but individual variations in metabolism and efficiency can affect actual expenditure.

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

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

Q5: Does this include basal metabolic rate?
A: No, this calculates only the additional calories burned during activity, not your resting metabolism.
