How to Calculate Calories Burned While Walking

Calculating the calories burned during walking involves considering several factors, including your weight, walking pace, and duration. This calculation provides an estimate of energy expenditure during your walk.

Calories Burned Walking Formula

The formula used to calculate calories burned while walking is:

$$\text{Calories Burned} = \frac{\text{MET} \times 3.5 \times \text{Weight (kg)} \times \text{Duration (minutes)}}{200}$$

Where:

• MET (Metabolic Equivalent of Task): A measure of walking intensity relative to resting metabolism
• 3.5: A constant representing the average resting oxygen consumption in mL/kg/min
• Weight: Your body weight in kilograms
• Duration: The time spent walking in minutes
• 200: A conversion factor to adjust the result to calories

Calculation Steps

1. Determine your weight in kilograms.
2. Select the appropriate walking pace (slow, moderate, brisk, or very brisk).
3. Determine the corresponding MET value based on the pace.
4. Input the duration of your walk in minutes.
5. Apply the formula to calculate calories burned.

Example Calculation

Let's calculate the calories burned for a person with the following details:

• Weight: 70 kg
• Walking Pace: Moderate (3 mph)
• Duration: 30 minutes

Step 1: Determine the MET value

For moderate pace walking, the MET value is approximately 3.5

Step 2: Apply the formula

$$\begin{align} \text{Calories Burned} &= \frac{3.5 \times 3.5 \times 70 \times 30}{200} \\ &= \frac{2572.5}{200} \\ &= 128.625 \text{ calories} \end{align}$$

Therefore, this person burns approximately 129 calories during their 30-minute moderate pace walk.
