Caloric Burn Rate Calculator (USA)
Calculate calories burned during exercise based on MET, weight, and duration.
How to Calculate Caloric Burn Rate
Calories burned during exercise are calculated using MET (Metabolic Equivalent of Task), body weight, and exercise duration:
- Formula: Calories Burned = MET × weight(kg) × duration(h)
- Key Components: MET Value, Body Weight (kg), Duration (hours)
- Note: MET = metabolic equivalent of task (resting metabolic rate = 1 MET)

Exercise Recommendations
Based on burning 490 calories:
- Running for 30 minutes burns approximately 245 calories
- Walking for 60 minutes burns approximately 210 calories
- Cycling for 45 minutes burns approximately 210 calories
- Swimming for 40 minutes burns approximately 180 calories
- This calculator provides estimates only - actual burn rates may vary
- Individual factors like fitness level, age, and metabolism affect calorie burn
- MET values are averages and may not reflect your specific energy expenditure
- Consult a healthcare professional before starting new exercise routines
Q&A
Q: What is MET and how accurate is it for calculating calories burned?
A: MET stands for Metabolic Equivalent of Task, a unit measuring the energy cost of physical activities:
Definition:
- 1 MET = resting metabolic rate (about 1 kcal/kg/hour)
- Activity MET = energy expenditure during activity ÷ resting energy expenditure
- Example: Running at 6 mph = 7 METs (7 times the resting metabolic rate)
Accuracy Considerations:
- Population averages: Based on studies of average individuals
- Individual variation: Can vary by 10-20% between people doing same activity
- Fitness level: Trained individuals may burn fewer calories for same activity
- Efficiency: More efficient movement patterns burn fewer calories
While MET values provide good estimates, actual calorie burn can vary significantly based on individual factors. For precise measurements, consider using heart rate monitors or metabolic carts.
Q: How does body weight affect caloric burn during exercise?
A: Body weight significantly affects caloric burn during exercise because the formula includes weight as a direct factor:
Direct Relationship:
- Calories burned ∝ body weight (when other factors are constant)
- Someone weighing 154 lbs burns about 50% more calories than someone weighing 103 lbs during same activity
- Heavier individuals move more mass against gravity, requiring more energy
Activity Examples:
- Walking: Heavier people carry more weight with each step
- Running: More force needed to propel heavier body forward
- Swimming: Greater displacement of water for heavier individuals
This is why weight loss often accelerates initially but slows over time - as you lose weight, you burn fewer calories doing the same activities. This is a natural part of the weight loss process and should be expected.
