Calories Burned Equation:
| From: | To: |
The Calories Burned Equation calculates energy expenditure during physical activity using the Metabolic Equivalent of Task (MET) method. This formula provides an estimate of calories burned based on activity intensity, body weight, and duration.
The calculator uses the MET equation:
Where:
Explanation: The equation multiplies MET value (activity intensity), weight, and time, then divides by 200 to convert to calories burned.
Details: Accurate calorie expenditure estimation is crucial for weight management, exercise planning, and understanding energy balance for fitness and health goals.
Tips: Enter MET value (common activities: walking=3.5, running=8, cycling=7), weight in kg, and time in minutes. All values must be positive numbers.
Q1: What are MET values and where can I find them?
A: MET values represent activity intensity relative to resting metabolism. Comprehensive MET tables are available from exercise physiology resources and health organizations.
Q2: How accurate is this calculation method?
A: This provides a reasonable estimate for general purposes. Individual variations in metabolism, fitness level, and exercise efficiency can affect actual calorie burn.
Q3: Why use weight in kilograms?
A: The equation is designed for metric units. If you have weight in pounds, convert to kilograms by dividing by 2.205.
Q4: What is the 200 conversion factor?
A: This factor converts the product of MET, weight, and time into calories, accounting for the relationship between oxygen consumption and energy expenditure.
Q5: Can this be used for all types of exercise?
A: Yes, as long as you have the appropriate MET value for the specific activity. MET values vary significantly between different exercises.
