How does the calculator estimate calories burned during exercise?
It uses the MET value for the selected activity, which represents the activity's energy cost relative to resting. The standard formula is Calories burned = (MET x 3.5 x body weight in kg / 200) x duration in minutes.
Why does body weight change the answer?
A larger body generally needs more energy to do the same work. That is why two people doing the same activity for the same amount of time can get different calorie totals.
How many calories do I burn per hour?
The calculator can rescale the session into a calories-per-hour figure so you can compare workouts on the same time basis. That is especially useful when a short hard session and a longer easy session need to be compared fairly.
Why do different calculators give different results for the same activity?
Different tools use different MET tables, different intensity assumptions, or wearable-device data such as heart rate and movement signals. That means the numbers can vary even when the workout sounds the same.
Can I use a calories burned calculator to plan weight loss?
Yes, but it works best as a broad planning estimate rather than a precise eat-back number. Exercise calorie estimates, wearable readouts, and food logging all carry error, so weekly trends are more useful than one-workout precision.
Which activity burns the most calories?
It depends on the MET value, your body weight, and how long you do the activity. In general, higher-intensity activities such as running or vigorous cycling burn more than lower-intensity activities such as easy walking or yoga.
Should I use calories burned per hour or total calories?
Use total calories when you care about a single session, and use calories burned per hour when you want to compare workouts of different lengths on the same time basis. The calculator shows both so you can compare activities fairly without doing the conversion yourself.
How long do I need to exercise to burn 300 or 500 calories?
There is no universal answer because the time needed depends on your body weight and the activity you choose. Higher-MET activities such as running or swimming usually reach those targets faster than walking or yoga, and heavier bodies usually reach them faster than lighter bodies at the same pace. That is why the page includes target-time rows for the currently selected workout instead of making you guess from the total.
Is it better to compare calories per hour, calories per session, or calories per week?
Each answers a different planning question. Calories per hour help compare intensity, calories per session help compare one workout with another, and weekly totals are often the best way to understand routine-level impact. If you are deciding what to repeat across a week, the weekly planner is usually more helpful than looking at only one workout in isolation.
Why does the page compare the same workout at several body weights?
Because many users want to know how much the estimate changes when the activity and session length stay the same but body weight changes. That comparison helps answer common search intent around calories burned by weight without forcing you to overwrite your own inputs repeatedly. It is also a quick reminder that exercise calorie burn is not a fixed number for every person doing the same workout.
Does this calculator include afterburn or EPOC?
No. It uses a standard MET-based exercise model and does not add a separate afterburn or excess post-exercise oxygen consumption adjustment. That keeps the estimate transparent, but it also means very intense sessions may still differ from a wearable or lab test.
How do I choose between similar activity options?
Choose the option that best matches your average effort, then compare the result against a second option if you are unsure. If your workout sits between two intensities, pick the closer average pace or use the more conservative estimate for planning.
Can this replace the old running, walking, biking, hiking, swimming, elliptical, and weight-lifting calorie calculators?
Yes for the shared activity-calorie planning job. The consolidated page keeps those activity choices in one selector, exposes MET values, and adds duration, distance, or count modes where they are useful. It is intended to answer the broad calories-burned workflow without splitting closely related searches across many thin pages.
How does distance mode estimate calories burned?
Distance mode uses the selected activity's reference speed to estimate active minutes, then applies the same MET formula. That is useful for route questions such as running 5 km, walking one mile, biking 10 miles, or hiking a planned trail, but it remains an estimate because real pace, terrain, stops, incline, and conditions can change the duration and effort.
How does reps-or-jumps mode estimate jump-rope or push-up calories?
For jump rope and push-ups, the calculator converts the entered count into active time using a practical pace assumption, then applies the selected MET value. This preserves common searches such as calories burned by 1,000 jumps or 100 push-ups, while making clear that rest periods, form, pace, and modified variations can change the real result.
