Calories Burned Formula:
| From: | To: |
The Calories Burned By Weight Calculator estimates the number of calories burned during physical activity using the MET (Metabolic Equivalent of Task) formula. It provides an accurate assessment of energy expenditure based on exercise intensity, body weight, and duration.
The calculator uses the standard calorie burn equation:
Where:
Explanation: The MET value represents the energy cost of physical activities. One MET is defined as the energy expenditure while sitting at rest.
Details: Accurate calorie burn estimation is crucial for weight management, exercise planning, and understanding energy balance for fitness goals and health maintenance.
Tips: Enter MET value (common activities: walking=3.5, running=8, cycling=7), weight in kilograms, and exercise time in minutes. All values must be positive numbers.
Q1: What are MET values and where can I find them?
A: MET values represent exercise intensity. Common values: resting=1, walking=3-4, running=8-12, swimming=6-8. Comprehensive MET tables are available in exercise physiology resources.
Q2: How accurate is this calculation?
A: The formula provides a good estimate for most people, but individual factors like fitness level, body composition, and exercise efficiency can affect actual calorie burn.
Q3: Should I use kilograms or pounds for weight?
A: The calculator requires weight in kilograms. To convert from pounds, divide by 2.2046 (1 kg = 2.2046 lbs).
Q4: Can this be used for weight loss planning?
A: Yes, it's useful for estimating exercise energy expenditure, but remember that nutrition and overall activity level also significantly impact weight loss.
Q5: Are there limitations to this calculation?
A: The formula assumes average metabolic rates and doesn't account for individual variations in fitness, age, gender, or specific health conditions that may affect metabolism.
