Calorie Burn Formula:
| From: | To: |
The calorie burn formula estimates the number of calories burned during physical activity using the Metabolic Equivalent of Task (MET) value, weight, and duration of activity. It provides a standardized way to calculate energy expenditure for various exercises.
The calculator uses the calorie burn formula:
Where:
Explanation: The formula calculates energy expenditure by multiplying the MET value (which represents exercise intensity) by body weight and exercise duration, then dividing by 60 to convert to calories.
Details: Accurate calorie estimation is crucial for weight management, fitness planning, and understanding energy balance during physical activities.
Tips: Enter weight in kilograms, time in minutes, and MET value. The default MET value for cycling is 6.8, but this can vary based on intensity. All values must be valid (weight > 0, time > 0, MET > 0).
Q1: What is MET and how is it determined?
A: MET (Metabolic Equivalent of Task) is a unit that represents the energy cost of physical activities. One MET is defined as the energy expenditure while sitting at rest.
Q2: Why use different MET values?
A: Different activities and intensity levels have different MET values. For cycling, MET can range from 4.0 for light effort to 16.0 for vigorous racing.
Q3: How accurate is this calculation?
A: This provides an estimate. Actual calorie burn can vary based on individual factors like fitness level, body composition, and exercise efficiency.
Q4: Should I use kg or pounds for weight?
A: The formula requires weight in kilograms. To convert from pounds, divide by 2.2 (1 kg = 2.2 lbs).
Q5: Can this calculator be used for other activities?
A: Yes, by changing the MET value, you can calculate calories burned for various activities like running, swimming, or weight training.
