Calories Burned Calculator (Exercise & MET Energy Expenditure)
Calculate calories burned during workouts, sports, walking, and running using MET values.
TL;DR: Calories Burned Calculator computes energy expenditure across activities using standard Metabolic Equivalent of Task (MET) formulas: $\text{Calories} = \text{Time (min)} \times [\text{MET} \times 3.5 \times \text{Weight (kg)}] / 200$.
What Is a MET and How Do You Calculate Calories Burned from Exercise?
A Metabolic Equivalent of Task (MET) is the ratio of working metabolic rate to resting metabolic rate (1 MET ≈ 1 kcal/kg/hour). Calories burned is calculated as: Calories = Duration (minutes) × [MET × 3.5 × Weight (kg)] / 200. For example, a 70 kg person running at 6 mph (MET 9.8) for 30 minutes burns: 30 × [9.8 × 3.5 × 70] / 200 = 360 calories.

Computes energy expenditure using Metabolic Equivalent of Task (MET) values across 100+ physical activities.
Calculation Example
A 75 kg person running at 6 mph (MET = 9.8) for 45 minutes: $$\text{Calories Burned} = 9.8 \times 3.5 \times \frac{75}{200} \times 45 = 579 \text{ kcal}$$

Frequently Asked Questions
- The formula is `Calories Burned = Duration (minutes) × [MET × 3.5 × Weight (kg)] / 200`.
- Walking 10,000 steps (about 5 miles) burns approximately 300 to 500 calories, depending on your body weight and walking pace.
- Moving a larger mass against gravity requires more mechanical energy and cardiovascular effort, resulting in higher caloric expenditure.
- High-intensity activities like competitive cross-country skiing (MET 14), jump rope (MET 12.3), fast running at 8+ mph (MET 11.8), and swimming laps (MET 10) burn the most calories per hour.
- Yes. Resistance training triggers Excess Post-Exercise Oxygen Consumption (EPOC), causing the body to burn additional calories for muscle repair and recovery over the next 12 to 24 hours.
- MET (Metabolic Equivalent of Task) measures energy expenditure: 1 MET equals the energy burned sitting quietly at rest. Running at 6 mph has an 9.8 MET value, burning ~9.8x more energy.
