What is Free Calories Burned Calculator šŸ”„?

The HIF Logic Calories Burned Calculator uses Metabolic Equivalent of Task (MET) values ā€” the scientific standard for measuring exercise intensity ā€” to estimate caloric expenditure for any workout. šŸ”„ The Formula: Calories Burned = Duration (min) Ɨ (MET Ɨ 3.5 Ɨ Body Weight in kg) Ć· 200 Where: Duration = workout length in minutes MET = Metabolic Equivalent of Task (activity-specific, scaled by intensity) Weight = body mass in kilograms (lbs Ć· 2.205) 3.5 = oxygen uptake constant (ml/kg/min at rest) 200 = conversion factor (ml Oā‚‚ ā†’ kcal) āš” What is a MET value? A MET of 1.0 is the energy your body expends at complete rest (sitting still). An activity with MET 4.0 burns four times as many calories as rest. Walking briskly is ~3.5 MET; running at a moderate pace is ~8.3 MET; HIIT can reach 12+ MET. šŸ“Š MET values used by this calculator (by intensity): Walking: Low 2.5 Ā· Moderate 3.5 Ā· High 4.5 Running: Low 6.0 Ā· Moderate 8.3 Ā· High 11.0 Cycling: Low 4.0 Ā· Moderate 6.8 Ā· High 10.0 Swimming: Low 4.5 Ā· Moderate 6.0 Ā· High 8.0 Weightlifting: Low 3.0 Ā· Moderate 5.0 Ā· High 6.0 HIIT: Low 7.0 Ā· Moderate 9.0 Ā· High 12.0 Yoga: Low 2.0 Ā· Moderate 3.0 Ā· High 4.0 Example ā€” 160 lb (72.6 kg) person, moderate-intensity cycling, 45 minutes: MET = 6.8 Calories = 45 Ɨ (6.8 Ɨ 3.5 Ɨ 72.6) Ć· 200 = 45 Ɨ 1,737.96 Ć· 200 ā‰ˆ 391 kcal Note: MET-based estimates are population averages. Individual calorie burn varies with fitness level, terrain, and personal metabolism.

  5. 5

    Results update instantly ā€” no button press needed. You'll see total calories burned and the exact MET value used in the calculation.

  6. 6

    The formula breakdown card shows the exact arithmetic so you can verify or replicate the calculation.

Real-World Use Cases

A Casual Walker Tracking an Evening Stroll

You went for a brisk 45-minute walk around the neighborhood. Select "Walking," enter your weight (say, 175 lbs), set duration to 45 minutes, and intensity to Moderate. The MET value of 3.5 is applied and you'll see your calorie burn instantly ā€” approximately 293 kcal for a 175 lb person. This gives you real data to decide whether a post-walk snack fits your daily calorie budget.

An Endurance Athlete Planning a Recovery Meal

You completed a high-intensity 60-minute cycling session and need to know exactly how many calories to replace. Select "Cycling," enter your weight (155 lbs / 70.3 kg), set duration to 60 min, and intensity to High (MET 10.0). The calculator shows approximately 739 kcal burned ā€” meaning you need a substantial recovery meal with adequate carbohydrates and protein to replenish glycogen and support muscle repair.

Comparing Two Workouts by Caloric Output

Deciding between a 30-minute yoga class and a 30-minute HIIT session? Select Yoga (Moderate, MET 3.0) for a 150 lb person: ~99 kcal. Switch to HIIT (Moderate, MET 9.0): ~298 kcal. HIIT burns 3Ɨ more calories in the same time window. That comparison takes seconds ā€” no spreadsheet required.
