1. What is the Calorie Burn Equation?

The calorie burn equation estimates energy expenditure during physical activity based on duration, intensity (MET), and body weight. It allows comparison between different activities like biking and walking.

2. How Does the Calculator Work?

The calculator uses the following equation:

Where:

• \( T \) — Time in hours
• \( MET \) — Metabolic equivalent of task
• \( W \) — Weight in kilograms
• 3.5 — Oxygen consumption at rest (mL/kg/min)

Explanation: The equation converts MET values to calories burned based on duration and body weight.

3. Understanding MET Values

Details: MET (Metabolic Equivalent of Task) represents exercise intensity. Biking typically ranges from 4-16 METs while walking ranges from 2.5-5 METs depending on speed and terrain.

4. Using the Calculator

Tips: Enter time in hours, appropriate MET values for your activity intensity, and weight in kg. Default values are provided for moderate biking (7.5 MET) and walking (3.5 MET).

5. Frequently Asked Questions (FAQ)

Q1: How accurate is this calculator?
A: It provides reasonable estimates for most people, but actual calorie burn can vary by 10-20% due to individual differences.

Q2: What's a typical MET value for biking?
A: Leisure biking (~10 mph) is about 6-8 METs, vigorous biking (~14 mph) is 10-12 METs, and racing is 12-16 METs.

Q3: Does biking burn more calories than walking?
A: Generally yes, as biking typically has higher MET values. At equal durations, biking usually burns 1.5-3× more calories than walking.

Q4: Should I use this for weight loss planning?
A: It can help estimate exercise energy expenditure, but remember that diet is typically more important for weight loss than exercise alone.

Q5: How does weight affect calorie burn?
A: Heavier individuals burn more calories for the same activity because they're moving more mass. The equation accounts for this directly.
