A MET is a multiple of resting metabolic rate, so this is total energy used during the activity rather than extra energy above rest. Gym machines and watches typically overestimate by 10 to 30 per cent.

About the Calories Burned Calculator

Calories Burned Calculator uses MET values, the standard way exercise energy cost is published. One MET is the energy used at rest; an activity rated at 8 METs uses eight times that rate. The arithmetic is MET times 3.5 times your weight in kilograms, divided by 200, which gives calories per minute.

Weight is the input that matters most, and it is why generic calorie tables are so unreliable. Moving a heavier body costs more energy, so a person of 100 kg burns roughly 40 per cent more than one of 70 kg doing exactly the same activity for the same time.

Two honest caveats. A MET value includes resting metabolism, so the figure is total energy during the activity rather than extra energy above what you would have used anyway -- the net cost is lower by roughly one MET's worth. And every method of estimating this, including gym machines and wrist-worn trackers, tends to overestimate, often by ten to thirty per cent.

This is general information and not medical advice. The formula cannot know your medical history, your medication, your body composition or anything else specific to you. Speak to a doctor or another qualified professional about any question concerning your health, and never delay seeking advice because of a figure on this page.

Your measurements are processed inside your own browser. Height, weight, age and anything else you enter never leave your device, nothing is logged, and nothing survives closing the tab.

Looking for something this does not cover? FreeToolStation.com is a second collection of the same kind of everyday tools, and it is worth a look if calories burned calculator is only part of what you are working on.

How to use the Calories Burned Calculator

  1. Choose activityThe fields below change to match what you pick, so only the figures that matter to your case are asked for.
  2. Enter weight (kg), duration (minutes) and met valueDecimals are fine, and thousands separators are accepted and ignored.
  3. Read the calories burned, per minute and per hourThe figures update as you type. The Calculate button is there if you would rather press something, but nothing waits for it.
  4. Copy or check the resultCopy the summary with the copy button, or open the table to check it row by row.

Features

  • Shows calories burned, per minute, per hour, if done 3 times a week and met value used together, so you are not running it twice
  • A results table you can read across
  • Updates as you type, with no button to press and no page reload

  • Free, no sign-up, and it runs entirely in your browser

Who uses this tool

The calories burned calculator is used by writers, developers, students, marketers and anyone else who needs the job done once without installing software. Common cases include:

  • Estimating the energy cost of a workout
  • Comparing activities on a like-for-like basis
  • Checking a figure a machine or watch reported
  • Working out a weekly exercise energy total

Frequently asked questions

What is a MET?

A multiple of resting metabolic rate. One MET is roughly 3.5 ml of oxygen per kilogram per minute, which is what your body uses sitting still.

Why does my watch give a different number?

Wrist trackers estimate from heart rate and movement, and tend to overestimate. Neither figure is a measurement; both are models.

Should I subtract resting calories?

For the net cost of exercising, yes: subtract about one MET's worth for the duration. Most published figures, including these, do not.
