Question
Is this an exact calorie count?
No. It is a planning estimate based on standard MET values. Real calorie burn varies with intensity, terrain, pace, fitness level, and exercise technique.
Fitness
Use OmniCalc's calories burned calculator to estimate how much energy a workout or activity session uses based on your body weight, chosen exercise, and total duration.
Calories burned calculator
Choose an activity, enter body weight and workout duration, and get a quick planning estimate for total energy burned.
This works well for workout planning, treadmill sessions, cardio comparisons, weight-management estimates, and linking effort targets back to calorie and macro planning.
Why this result matters
A practical exercise calorie-burn estimator that uses body weight, duration, and common activity types to estimate session energy use. Use the tool above to enter a few clear inputs and get a practical answer you can use right away.
This calories burned calculator helps you estimate workout energy expenditure for common activities like running, walking, cycling, swimming, HIIT, strength training, and yoga. It uses standard MET values with body weight and time to produce a fast planning estimate that can support training, weight-management, and macro-planning decisions.
Formula and method
The calculator multiplies a standard MET value by body weight and exercise duration to estimate calorie burn using the common formula calories = MET × 3.5 × weight in kg × minutes ÷ 200.
Example
If someone weighing 70 kg runs for 45 minutes, the calculator can estimate the total calories burned, the average calories per minute, and the hourly equivalent at that same effort level.
FAQ
Short answers to the questions people often ask before or after using the tool.
Question
No. It is a planning estimate based on standard MET values. Real calorie burn varies with intensity, terrain, pace, fitness level, and exercise technique.
Question
Each activity uses a different MET value, which changes the estimated energy cost per minute. Higher-intensity sessions typically burn more calories in the same amount of time.
Question
Yes, as a rough planning tool. It works best when paired with daily calorie, macro, and activity tracking rather than used as a perfect one-number answer.
