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.

How to Use the Calories Burned Calculator

Our Calories Burned Calculator performs high-precision mathematical operations directly in your browser with zero latency and complete client-side privacy.

  1. Select your activity from the categorized database (Running, Cycling, Swimming, Gym, Sports, Walking).
  2. Enter your current Body Weight in pounds or kilograms.
  3. Enter the Exercise Duration in minutes or hours.
  4. Click 'Calculate Calories Burned' to view total energy expenditure.
  5. Compare different workout intensities to optimize exercise programming.

Mathematical Formula & Equations

Computes energy expenditure using Metabolic Equivalent of Task (MET) values across 100+ physical activities.

\[ \text{Calories Burned} = \text{MET} \times 3.5 \times \frac{\text{Weight (kg)}}{200} \times \text{Duration (minutes)} \]

Calculation Example

A 75 kg person running at 6 mph (MET = 9.8) for 45 minutes: $$\text{Calories Burned} = 9.8 \times 3.5 \times \frac{75}{200} \times 45 = 579 \text{ kcal}$$

100% Client-Side Privacy & Data Security

All calculations, amortization schedules, variables, and sensitive numerical datasets execute 100% locally in your web browser memory. Your financial, medical, and personal values are never transmitted, logged, or uploaded to any external server.

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.
