Calories Burned Calculator
Estimate the calories you burn from any activity using its MET value, your body weight, and how long you moved.
Moderate intensity, MET 5.0.
Calculated in your browser. Nothing is uploaded.
Estimates use standard MET values and your body weight. Actual burn varies with fitness, effort, terrain, and body composition.
How to calculate calories burned
Pick an activity
Choose your workout or activity from the grouped list and its intensity value loads automatically.
Enter weight and time
Type your body weight in kilograms or pounds and how many minutes you were active.
Read the total
See the total calories burned, calories per minute, and a fat-gram equivalent, then click Copy to save the numbers.
Why use this tool
MET table for dozens of activities
Walking, running, cycling, swimming, strength work, sports, and chores each carry a standard MET intensity value, so the estimate reflects the effort of what you actually did.
Total, per-minute, and fat equivalent
Read the total calories burned for the session, the rate in calories per minute, and roughly how many grams of fat that energy represents at 9 calories per gram.
Kilograms or pounds
Switch the weight unit between kg and lb and the value converts for you, so you can enter whichever number you know.
Updates as you type
Change the activity, weight, or duration and every figure recalculates instantly, with no button to press.
Runs entirely in your browser
Everything is calculated on your device. Nothing is uploaded, stored, or logged.
About this tool
A calories burned calculator estimates how much energy an activity uses from three things: the activity itself, your body weight, and how long you kept at it. Every activity has a MET value, a number that describes how hard it is compared with sitting still. The tool multiplies that MET by your weight and time to work out the calories, and shows the total, the rate per minute, and a fat-gram equivalent as you type.
Pick from grouped activities such as walking, running, cycling, swimming, strength training, sports, and household chores, then set your weight in kilograms or pounds and enter the minutes you were active. A brisk walk, an easy jog, and a hard bike ride all carry different intensities, so the estimate tracks the real effort rather than a flat number. Pair it with the TDEE calculator to see how a workout fits your daily budget, or the running pace calculator to plan the session first.
These figures are estimates. MET values are population averages, so your actual burn depends on fitness, effort, terrain, and body composition, and the fat-gram equivalent is a rough guide rather than a promise of fat lost. Treat the numbers as a consistent way to compare sessions, not an exact measurement. Because your weight and workout details are personal, they never leave your device: everything is calculated in the page and nothing is uploaded.
Frequently asked questions
- How are calories burned calculated?
- The tool uses the standard MET formula: calories per minute equal the activity MET times 3.5 times your weight in kilograms, divided by 200. Multiply that by your minutes and you get the total for the session.
- What is a MET value?
- A MET, or metabolic equivalent, measures how hard an activity is relative to sitting quietly, which is 1 MET. Brisk walking is about 5 METs and running a 10-minute mile is close to 10, so higher MET activities burn more per minute.
- How accurate is the estimate?
- It is a solid estimate, not a measurement. MET values are averages across many people, so your real burn varies with fitness, effort, terrain, and body composition. Use it to compare sessions consistently rather than as an exact calorie count.
- What does the fat-gram equivalent mean?
- One gram of body fat stores roughly 9 calories, so dividing the calories burned by 9 gives a rough sense of the energy in fat terms. It is a reference figure, not a prediction of how much fat you will lose.
- Can I enter my weight in pounds?
- Yes. Toggle the unit to lb and type your weight in pounds. The tool converts to kilograms internally for the calculation and keeps your entered value when you switch units.
- Is my data uploaded anywhere?
- No. Everything runs in your browser; nothing is sent to a server. The activity, weight, and duration you enter are never uploaded, stored, or logged.
