Pick an activity, enter your weight and how long you were moving, and most calorie calculators just hand you a number. Ours does the same instant math, with a few differences that matter:
- Instant — your estimated calories burned update as you type, in either metric or imperial units, with no page reload.
- Transparent — every result shows its breakdown (MET value × weight × time), so you can see exactly how the number was built instead of trusting a black box.
- Honest — MET values are standard published averages, and we say so plainly: your actual burn varies with intensity, fitness level, and body composition. It’s a general estimate, not medical or nutritional advice.
- Private — everything runs in your browser. We never see your numbers.
Try the calories burned calculator with your own weight and activity, and if you write about fitness, it’s embeddable on your own site with one iframe.
