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 time. It provides a standardized way to compare energy costs of different activities.

2. How Does the Calculator Work?

The calculator uses the calories burned equation:

\[ \text{calories} = \text{MET} \times \text{weight\_kg} \times \text{time\_h} \]

Where:

\( MET \) — Metabolic Equivalent of Task (dimensionless)
\( weight\_kg \) — 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 Calories Calculation

Details: Accurate calorie estimation helps in weight management, exercise planning, and understanding energy balance between intake and expenditure.

4. Using the Calculator

Tips: Enter MET value (common activities range from 1-12), weight in kg, and time in hours. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What are typical MET values?
A: Sitting = 1.0, Walking 3mph = 3.5, Running 6mph = 10, Swimming laps = 8-11 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?
A: The equation requires weight in kilograms (1 kg = 2.2 lbs).

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

Q5: Does this include basal metabolic rate?
A: No, this calculates only additional calories burned during activity above resting metabolism.
