🔥 Calories Burned Calculator

What is Calories Burned Calculator?

The Calories Burned Calculator estimates how many calories you burn during exercise from standard MET values for running, cycling, swimming, walking, yoga and a dozen more activities. Enter your weight, pick an activity and a duration, and it applies the formula calories = MET x 3.5 x weight in kg / 200 x minutes to return a per-session figure, then projects your weekly total from how many days per week you train. An effort selector switches between moderate and vigorous MET values wherever an activity has both. Everything runs locally in your browser with no account and no data upload.

Frequently Asked Questions

• How accurate is the calories burned estimate?▾
  The tool uses the standard MET method, where each activity has an energy cost in METs and you burn about MET x 3.5 x your weight in kg / 200 calories per minute. MET values are population averages, so your real burn varies with fitness, terrain and effort, but the estimate is a solid planning number.
• Does my body weight change the result?▾
  Yes. Moving a heavier body takes more energy, so the estimate scales with the weight you enter - the same workout burns more calories for a heavier person and fewer for a lighter one.
• How many calories do I burn running 5 km?▾
  At a steady 6 mph (10-minute-mile) pace, 5 km takes about 31 minutes and burns roughly 370 calories for a 70 kg person. Heavier runners or faster paces push that number higher.
