The following formula can be used to calculate the total calories burned from walking:
\[ \text{Total Calories Burned} = \text{Steps} \times 0.04 \times \text{BMI Factor} \times \text{Age Factor} \times \text{Speed Factor} \]
Where:
Calculating the total amount of calories burned from walking may seem straightforward, but it can be more accurate by considering factors like age, weight, gender, and walking speed. The provided calculator considers these factors to give a more precise estimate of the calories burned.
Let's say a 25-year-old male who weighs 70 kg and is 175 cm tall walks 10,000 steps at a speed of 3.5 mph. Using the formula:
Steps = 10,000
Age = 25 years
Gender = Male
Height = 175 cm
Weight = 70 kg
Speed = 3.5 mph
BMI = 70 / (1.75 * 1.75) = 22.86
Base Calories = 10,000 * 0.04 = 400
BMI Factor = 1 (since BMI is between 18.5 and 25)
Age Factor = 1.1 (since age is less than 30)
Speed Factor = 3.5 / 3.0 = 1.17
Total Calories Burned = 400 * 1 * 1.1 * 1.17 = 514.8 calories
