1. What is the Calories Burned Formula?

The calories burned formula estimates energy expenditure during physical activity using time, metabolic equivalent (MET), and body weight. It provides a standardized way to calculate calories burned during various activities, including biking which is comparable to running.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( Time \) — Duration of activity in hours
• \( MET \) — Metabolic equivalent of task (unitless)
• \( Weight \) — Body weight in kilograms
• 3.5 — Oxygen consumption at rest (mL/kg/min)
• 200 — Conversion factor to calories

Explanation: The formula calculates energy expenditure based on the intensity of the activity (MET value) and the individual's body weight over a specific time period.

3. Importance of Calories Calculation

Details: Accurate calorie estimation is crucial for weight management, exercise planning, and understanding energy balance during physical activities like biking and running.

4. Using the Calculator

Tips: Enter time in hours, MET value (typically 4-16 for biking/running), and weight in kg. All values must be valid positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What are typical MET values for biking?
A: MET values range from 4-16 depending on intensity: light effort (4-6), moderate (6-10), vigorous (10-16).

Q2: How does biking compare to running in calories burned?
A: Running typically burns more calories per hour than biking at similar perceived exertion due to higher impact and muscle engagement.

Q3: Is this formula accurate for everyone?
A: It provides estimates; individual variations in metabolism, fitness level, and efficiency can affect actual calorie burn.

Q4: Can I use this for other activities?
A: Yes, with appropriate MET values for different activities (walking, swimming, etc.).

Q5: Why use kg for weight calculation?
A: The formula is standardized using metric units; convert pounds to kg (1 lb = 0.453592 kg) if needed.
