Calories Burned Formula:
From: | To: |
The calories burned formula estimates the number of calories expended during physical activity. It combines your Basal Metabolic Rate (BMR) with the Metabolic Equivalent of Task (MET) value and the duration of the activity.
The calculator uses the formula:
Where:
Explanation: This formula calculates calories burned by scaling your BMR (daily resting energy expenditure) according to the intensity (MET) and duration of the activity.
Details: Understanding calories burned helps with weight management, fitness planning, and ensuring appropriate energy intake for your activity level.
Tips: Enter your BMR in kcal/day, the MET value for your activity, and the duration in hours. All values must be positive numbers.
Q1: What is BMR and how do I calculate it?
A: BMR (Basal Metabolic Rate) is the number of calories your body burns at rest. It can be estimated using formulas like Harris-Benedict or Mifflin-St Jeor.
Q2: Where can I find MET values for different activities?
A: MET values are published in compendiums of physical activities. Common values: walking (2.5-4), running (7-12), cycling (4-10), swimming (4-8).
Q3: How accurate is this calculation?
A: It provides a reasonable estimate but individual variations in metabolism, fitness level, and exercise efficiency can affect actual calories burned.
Q4: Can I use this for weight loss planning?
A: Yes, it can help create a calorie deficit plan when combined with tracking food intake, though individual results may vary.
Q5: Why divide by 24 in the formula?
A: BMR is measured per day (24 hours), so dividing by 24 converts it to an hourly rate before multiplying by the activity duration.
