Energy expenditure reflects the oxygen cost of movement, expressed in metabolic equivalents (MET). One MET represents the resting metabolic rate; higher values indicate greater intensity. Estimating calories burned helps you balance nutritional intake with physical-activity output, guiding weight-management, sports-training, and rehabilitation programmes.
This calculator multiplies your body-mass value, the chosen activity’s MET factor, and exercise duration to project total kilocalories and per-hour burn rates. A reactive engine instantly updates numeric summaries, an interactive charting layer visualises minute-by-minute progress, and structured tables enable side-by-side activity comparisons and CSV export for deeper analysis.
Planning a 45-minute 8 km/h run? Enter 70 kg, select Running, set 45 minutes, and review both total and hourly figures before adjusting pace or time. This tool offers informational estimates and does not replace professional medical guidance.
Caloric cost derives from indirect calorimetry research linking oxygen uptake to mechanical workload. The method assumes a linear relationship between MET and oxygen consumption across diverse body masses and activities. Variables include body weight (W), task intensity (MET), and elapsed exercise time (t). Output is a single-value projection and related derivative rates.
Calories Burned | Category | Implication |
---|---|---|
< 200 kcal | Light | Brief or low-intensity effort |
200 – 500 kcal | Moderate | Typical daily workout range |
> 500 kcal | High | Prolonged or vigorous session |
Categories help users set realistic fueling and recovery targets but do not indicate health risk on their own.
Parameter | Unit | Typical Range | Notes |

Weight | kg / lb | 40 – 150 kg | Sensitive to scale accuracy |
MET | dimensionless | 1 – 15 | From compendia of activities |
Duration | min / hr | 5 – 240 min | Rounded to nearest minute |

MET factors are population averages; personal efficiency, terrain, and technique can shift true energy cost by ±10–15 %.
Calculate each segment separately and sum the kilocalories for a composite session total.
A flat line indicates zero or very short duration; increase minutes or switch to hours for meaningful curves.
M values stay constant; however, lowering body mass reduces total kilocalories burned at identical intensity and duration.
