Worked Examples
Example 1: Walking
Calculate calories for 70kg person walking 60 minutes at moderate intensity
- weightKg: 70
- durationMinutes: 60
- activityType: walking
- intensity: 5
- calories: 245
Example 2: Running
Calculate calories for 65kg person running 30 minutes at high intensity
- weightKg: 65
- durationMinutes: 30
- activityType: running
- intensity: 8
- calories: 416
About this calculator
Overview
This calorie calculator estimates energy expenditure for an activity using MET × body weight × duration.
When to use
Use it to approximate calories burned for a listed activity and intensity over a known time. It is a population heuristic, not a lab measurement.
Inputs explained
- Weight (kg) [required]
- Duration (minutes) [required]
- Activity Type [required]: Type of physical activity
- Intensity Level [optional]
Formula / method
Calories ≈ MET × weight(kg) × time(hours). MET depends on activity type and intensity as implemented in the calculator tables.
Worked example
Example: Calculate calories for 70kg person walking 60 minutes at moderate intensity (inputs weightKg = 70, durationMinutes = 60, activityType = walking, intensity = 5; outputs calories = 245).
Interpreting results
Higher MET or longer duration increases estimated calories roughly linearly. Individual efficiency and body composition cause real burn to differ.
Assumptions
- MET values follow the activity/intensity mapping on this page.
- Weight is body mass in kilograms after any unit conversion.
Limitations
- Wearables and indirect calorimetry can disagree with MET estimates.
- Not a prescription for diet, exercise, or weight change.
