How to Calculate Calories Burned from Pounds

Understanding the relationship between body weight and calories burned during physical activities is crucial for anyone on a fitness journey. This calculator helps you estimate the number of calories burned based on your weight in pounds and the type and duration of activity performed.

Pounds to Calories Burned Formula

The formula used to convert pounds to calories burned is:

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

Where:

• MET (Metabolic Equivalent of Task) is a measure of energy expenditure for different activities
• 3.5 is a constant representing the average resting metabolic rate
• Weight is the person's weight in kilograms (converted from pounds)
• Duration is the time spent on the activity in minutes
• 200 is a conversion factor

Calculation Steps

1. Convert the weight from pounds to kilograms (1 lb = 0.453592 kg)
2. Determine the MET value for the chosen activity
3. Input the person's weight in kilograms
4. Input the duration of the activity in minutes
5. Apply the formula to calculate calories burned
6. Interpret the results

Example Calculation

Let's calculate the calories burned for a person weighing 154 lbs who goes running for 30 minutes.

Step 1: Convert pounds to kilograms

$$154 lbs \times 0.453592 = 69.85 kg$$

Step 2: Determine the MET value for running (approximately 7.0)

Step 3: Input the values into the formula

$$Calories Burned = \frac{7.0 \times 3.5 \times 69.85 \times 30}{200}$$

Step 4: Perform the calculation

$$Calories Burned = \frac{51340.75}{200} = 256.70 calories$$

Therefore, a person weighing 154 lbs who runs for 30 minutes would burn approximately 257 calories.

Interpreting the Results

When interpreting the results of this calculation, keep in mind:

• This is an estimate and individual results may vary
• The intensity of the activity can significantly affect calories burned
• Factors such as age, sex, and fitness level also influence energy expenditure
• Consistent physical activity, combined with a balanced diet, is key to maintaining a healthy weight
