Calories Burned accuracy and testing
This page documents how Calwarden builds trust for this calculator: source notes, regression-style default tests, limitations, assumptions, unit handling, rounding, and visible change history.
Formula source
- This calculator uses the **MET (Metabolic Equivalent of Task)** method. **Formula:** Calories = MET × Weight (kg) × Duration (hours). 1 MET is the energy you burn at rest (BMR). An activity with 8 METs burns 8 times more energy than sitting still.
Test cases
Default input regression check
Generated from the checked-in default inputs and calculate function.
Inputs
- Activity: run_6
- Your Weight: 160 lbs
- Duration: 30 min
Expected outputs
- Calories Burned: Invalid input
Known limitations
- Assumes average metabolic efficiency. Individual factors like muscle mass, age, and fitness level can skew actual burns.
Assumptions
- The estimate uses average MET-style activity values rather than your exact heart rate or lab-tested burn rate.
- Body weight and duration are the main drivers in this simplified model.
- Actual burn varies with fitness level, intensity, terrain, and workout efficiency.
Unit handling
- Activity accepts one of the configured options.
- Your Weight accepts values in lbs.
- Duration accepts values in min.
- Calories Burned is displayed in kcal.
Rounding rules
- Number displays use up to 2 decimal places in the calculator UI.
