1. What is the Calorie Calculation for Walking 3 MPH?

The calorie calculation estimates energy expenditure during walking at 3 miles per hour (moderate pace) using the Metabolic Equivalent of Task (MET) value. The MET for walking 3 mph is 3.3, representing 3.3 times the resting metabolic rate.

2. How Does the Calculator Work?

The calculator uses the standard calorie equation:

Where:

• \( MET \) — 3.3 (for walking at 3 mph)
• \( Weight \) — Body weight in kilograms
• \( Time \) — Duration of activity in hours

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

3. Importance of Calorie Calculation

Details: Accurate calorie estimation helps with weight management, exercise planning, and understanding energy expenditure for health and fitness goals.

4. Using the Calculator

Tips: Enter weight in kilograms and time in hours (e.g., 30 minutes = 0.5 hours). All values must be valid (weight > 0, time > 0).

5. Frequently Asked Questions (FAQ)

Q1: How accurate is this calculation?
A: It provides a reasonable estimate but individual variations in metabolism, terrain, and walking efficiency can affect actual calories burned.

Q2: What if I walk faster or slower than 3 mph?
A: Different speeds have different MET values. For example, walking at 2.5 mph has a MET of 2.9, while 4 mph has a MET of 4.3.

Q3: Does incline affect calorie burn?
A: Yes, walking uphill significantly increases calorie expenditure. Add 0.1 MET per 1% grade to the base MET value.

Q4: Can I use pounds instead of kilograms?
A: Convert pounds to kilograms by dividing by 2.205 (e.g., 150 lbs = 68 kg).

Q5: How does body composition affect results?
A: Muscle burns slightly more calories than fat at rest, but the difference during walking is minimal for this calculation.
