Calculation Methods Explained

Calories burned while walking is heavily dependent on the **total distance** covered and the **user's weight**. The steps count is converted to distance by estimating the user's stride length.

1. Estimating Stride Length (L)

Since the distance is not directly measured, the stride length is estimated as a percentage of the user's height. This factor is typically slightly lower for women:

$$ \text{Stride Length}_{\text{cm}} = \text{Height}_{\text{cm}} \times \begin{cases} 0.45 & \text{if Male} \\ 0.415 & \text{if Female} \end{cases} $$
            

2. Calculating Total Distance (D)

$$ \text{Distance}_{\text{km}} = \frac{\text{Steps} \times \text{Stride Length}_{\text{cm}}}{100000} $$
            

3. Calculating Calories Burned (C)

The standard formula for estimating calories burned per kilometer (or mile) traveled accounts for the body weight, as heavier individuals expend more energy per unit of distance:

$$ \text{Calories} \approx \text{Weight}_{\text{kg}} \times \text{Distance}_{\text{km}} \times \text{Calorie Factor} $$
            

The Calorie Factor for walking is often approximated between $0.5$ and $0.6$. We use $0.5$ for a general walking pace, giving the final simplified formula:

$$ \text{Calories} \approx 0.5 \times \text{Weight}_{\text{kg}} \times \text{Distance}_{\text{km}} $$
