# How Does Fitness App Calculate Calories

Introduction: Understanding how calories are calculated in fitness apps is vital for anyone trying to maintain or improve their physical health. Fitness apps have become ubiquitous, helping individuals monitor their exercise and diet. But have you ever wondered how these apps calculate the calories you’ve burned during a workout or activity? In this article, we’ll explore the science behind it and provide a handy calculator to estimate the calories burned during different activities.

Formula: The formula used for calculating calories burned during an activity is relatively simple and follows the principle that the more effort you put into an activity, the more calories you burn. The formula can be described as:

Calories Burned = Activity Level × Weight (in kg)

How to Use: Using the calculator provided above is straightforward. Here are the steps:

1. Select the activity from the dropdown list.
2. Enter your weight in kilograms in the input field.
3. Click the “Calculate” button.

The calculator will then display the estimated calories burned for the selected activity and your weight.

Example: Let’s say you want to calculate the calories burned during a 30-minute run, and your weight is 70 kg. Using the calculator:

1. Select “Running” from the dropdown list.
2. Enter 70 in the weight field.
3. Click “Calculate.”

The calculator will show the estimated calories burned during the 30-minute run, based on your weight and the activity level.
