How to Use This Calculator

Enter your daily step count, body weight (kg), and height (cm) as recorded by your wearable.
Set your age and resting heart rate (bpm) for accurate calorie and heart-rate zone calculations.
Enter your average walking cadence (steps/min) and total active minutes for the day.
Read active calories, estimated distance (km/miles), and MET value from the outputs.
Compare your heart-rate zone distribution to target training zones shown in the results.
