Calories Burned Calculator
Estimate calories burned for common activities using your weight and workout duration, with MET-based results to compare workouts, goals, and weekly totals.
How to use this tool
- Choose an activity or enter a custom MET value.
- Set weight, unit, and workout duration to calculate current burn.
- Add entries to the session log and export CSV/JSON reports.
Accuracy context
- MET-based burn is an estimate and not a clinical measurement.
- Custom MET helps model interval sessions and non-standard activities.
- Results can differ from wearable devices and lab-grade assessments.
Planning workflows
- Use session logs to compare activity mixes across a week.
- CSV export supports spreadsheet-based nutrition and training tracking.
- JSON reports preserve assumptions for repeatable scenario analysis.
FAQ
- Are calorie outputs exact?
- No. They are formula-based estimates built from MET, weight, and duration.
- Can I track mixed workouts?
- Yes. Add each workout segment as a separate session log row.
- Is session data stored remotely?
- No. Session data stays in your current browser session.
