Calories Burned Calculator by Activity
Our calories burned calculator estimates the energy you use in 27 activities, from a slow walk to a hard run. Pick an activity, enter your weight and the minutes you spent, and the calorie burn calculator does the rest. It works in kilograms or pounds.
How the Calories Burned Calculator Works
Every activity has a MET value, short for metabolic equivalent of task. One MET is the energy you burn sitting quietly, roughly 1 kcal per kilogram of body weight per hour. Brisk walking is 4.3 MET, so it burns about 4.3 times your resting rate. The calories burned calculator multiplies that value by your weight and your time.
The formula is calories = MET × weight in kg × hours. A 70 kg person who walks briskly for 45 minutes burns 4.3 × 70 × 0.75, or about 226 kcal. Double the time and you double the burn.
Where the MET Values Come From
The MET numbers in this tool come from the Compendium of Physical Activities, a research list first published in 1993 and updated in 2011. Researchers built it from measured oxygen use across hundreds of activities. Most calorie charts and many fitness apps rely on the same source.
Each value is an average for a typical adult. Your real burn depends on fitness, technique and the ground under your feet. Treat every number from an exercise calorie calculator as a close estimate rather than an exact count.
How to Use the Calorie Burn Calculator
- Choose an activity from the list, or pick Custom MET to use it as a MET calculator.
- Select kilograms or pounds and enter your body weight.
- Type the number of minutes you spent on the activity.
- Read the total, the extra burn above rest and the hourly rate.
The calorie burn calculator updates as you type, so comparing activities takes seconds. Try the same 30 minutes as walking, cycling and swimming. Small changes in pace often matter more than people expect.
Total Burn vs Extra Burn
The first result counts every calorie you used during the session, including the ones you would have burned sitting on the couch. The second result from the calorie burn calculator removes that resting share by using MET minus one. For the brisk walk above, the total is 226 kcal but the extra burn is about 173 kcal.
The extra number is the fairer one for a weight loss plan. If you add exercise calories back into your food log, use the extra figure so you do not overeat. For that walk the total is about 30 percent higher than the true extra burn.
Calories Burned Walking
Walking is the activity people check most, and pace makes a big difference. For a 70 kg adult, calories burned walking for one hour range from 210 kcal at a slow stroll to 350 kcal at 4 mph. Hills and a heavy backpack push the number higher.
The table uses the same calories burned calculator settings for a 70 kg adult over 60 minutes. Scale it up or down with your own weight. Someone at 90 kg burns about 29 percent more than the figures shown.
| Activity | MET | Calories in 1 hour (70 kg) |
| Walking, slow (2.5 mph) | 3.0 | 210 kcal |
| Walking, brisk (3.5 mph) | 4.3 | 301 kcal |
| Walking, very brisk (4 mph) | 5.0 | 350 kcal |
| Running, 6 mph | 9.8 | 686 kcal |
| Cycling, moderate | 8.0 | 560 kcal |
| Weight lifting, light or moderate | 3.5 | 245 kcal |
| Yoga (Hatha) | 2.5 | 175 kcal |
Running Burns the Most
The calorie burn calculator puts running far ahead per minute, because every running MET value starts above 8. A 70 kg runner at 6 mph burns about 686 kcal in an hour, and the same runner at 8 mph burns about 826 kcal. A handy check for calories burned running is roughly 1 kcal per kilogram of body weight for every kilometer covered.
Worked Examples
A Morning Run
An 80 kg runner holds 6 mph for 30 minutes. The calorie burn calculator multiplies 9.8 × 80 × 0.5 and shows 392 kcal in total. The extra burn above resting is 352 kcal.
A Gym Session in Pounds
A 160 lb person lifts weights at a vigorous pace for one hour. The tool converts 160 lb to 72.6 kg and shows 435 kcal. The extra burn above resting is 363 kcal.
Why Your Watch Shows a Different Number
Fitness watches use heart rate, motion and their own formulas, so they rarely match a calorie burn calculator. A 2017 Stanford study tested seven wrist devices and found that even the best one was off by about 27 percent for calorie burn. Neither source is perfect, so pick one method and stick with it.
Calories Burned and Weight Loss
About 7,700 kcal equals one kilogram of body fat, or about 3,500 kcal per pound. Burning an extra 300 kcal a day through exercise adds up to a little over 1 kg a month. Food still matters more for most people, because skipping 300 kcal is easier than burning it.
Pair the calories burned calculator with our Calorie Calculator to see your full daily target. If you want your resting number on its own, the BMR Calculator shows it. Together they give you the whole picture of energy in and energy out.
