Calories Burned Formula:
| From: | To: |
The calories burned formula estimates the number of calories expended during physical activity based on time spent, metabolic equivalent (MET) value of the activity, and body weight. It provides a useful approximation for tracking energy expenditure during exercise and daily activities.
The calculator uses the calories burned formula:
Where:
Explanation: The formula calculates energy expenditure by multiplying activity duration by the MET value (which represents activity intensity) and body weight, then dividing by 200 to convert to calories.
Details: Estimating calories burned helps with weight management, exercise planning, and understanding energy balance. It's useful for athletes, fitness enthusiasts, and anyone monitoring their physical activity levels.
Tips: Enter activity time in minutes, the appropriate MET value for your activity, and your weight in kilograms. All values must be valid positive numbers.
Q1: What are MET values and where can I find them?
A: MET (Metabolic Equivalent of Task) values represent the energy cost of activities. Common values: walking (3-4), running (8-12), cycling (4-10). Comprehensive MET tables are available from exercise physiology resources.
Q2: How accurate is this calculation?
A: This provides a reasonable estimate for most people, but individual factors like fitness level, body composition, and exercise efficiency can affect actual calorie expenditure.
Q3: Should I use this for weight loss planning?
A: This can be a helpful tool for estimating exercise calories as part of a comprehensive weight management program, but should be combined with professional dietary advice.
Q4: Does this account for afterburn effect (EPOC)?
A: No, this formula calculates calories burned only during the activity. High-intensity exercises may continue to burn additional calories after the activity ends.
Q5: Can I use this for all types of exercise?
A: This formula works best for steady-state cardiovascular activities. It may be less accurate for strength training, interval training, or activities with highly variable intensity.
