- How many calories is 10,000 steps?
- For most adults, somewhere between 300 and 500. At 155 lb walking at a normal 3 mph pace it's about 375 calories; at 120 lb it's about 290, and at 200 lb about 484. Weight is what moves the number, because the work of walking is mostly the work of carrying yourself. Any site that answers with a single figure and no weight field is quoting an average body and hoping it's yours.
- How is this calculated?
- Calories = MET × 3.5 × your weight in kg ÷ 200 × minutes walked. The MET value comes from the 2011 Compendium of Physical Activities, the reference table exercise researchers use: 2.8 for 2 mph, 3.0 for 2.5, 3.5 for 3, 4.3 for 3.5, and 5.0 for 4 mph. Minutes come from your distance divided by your pace, and the distance comes from your steps times your stride. The tool shows you the MET and the stride it used, so you can redo the arithmetic yourself if you want to.
- Why do I burn MORE calories walking slower?
- Because the step count is fixed, so the distance is fixed — and a slower pace means more time on your feet. Ten thousand steps at 2 mph takes 2 hours 11 minutes and burns about 448 calories at 70 kg; the same steps at 3 mph take 1 hour 27 minutes and burn 374. The MET does go up with pace, just not fast enough to make up for the time. Past about 3 mph the trend reverses and faster does burn more. If you fix the time instead of the steps — an hour is an hour — walking faster always wins.
- Is this gross or net calorie burn?
- Gross, which is what every mainstream calculator reports. It counts everything your body used during the walk, including the roughly 1 calorie per minute you'd have burned sitting still. Net burn — the extra your walk cost you — is roughly 10 to 15% lower. That matters if you're adding the walk on top of a maintenance calorie target that already includes your resting metabolism, because counting it gross double-dips a little. For most people the difference is around 40 calories on a 10,000-step day.
- Why does my watch give a different number?
- Watches and phones use heart rate, accelerometer data and the personal details in your profile, so they're modelling your actual effort rather than a table value. They're also often wrong in a specific direction: validation studies have found consumer trackers off by 20 to 90% on energy expenditure, usually overestimating. Check the weight and height in your device's profile first — a stale weight from two years ago is the most common cause of a big gap. Neither number is precise enough to plan a deficit down to the calorie.
- Does height change the calories?
- Indirectly, and less than you'd guess. Height doesn't enter the calorie formula — it changes your stride, which changes how far 10,000 steps actually takes you, which changes the time. A 5 ft 10 in walker covers 4.58 miles in 10,000 steps versus 4.36 for the average step, about 5% more distance and so about 5% more calories. Weight moves the answer several times harder. Leave height blank and the tool uses a 27.6 in adult average.
- Does walking uphill burn more?
- Considerably. The Compendium lists walking at 3 mph on a 1 to 5% grade at MET 5.3 instead of 3.5, so a hilly version of the same walk burns roughly half again as much. Treadmill inclines work the same way. This calculator assumes flat ground, which is the right default for a step count off a phone — most daily steps are level. If your walk was genuinely hilly, treat the figure here as a floor.
- How many steps burn 100 calories?
- About 2,700 at 155 lb and a normal pace — the tool shows calories per 1,000 steps right under the main number, so you can divide. At 120 lb it's closer to 3,400 steps, and at 200 lb about 2,100. A useful way to read it: most adults burn somewhere between 30 and 50 calories per 1,000 steps, which is why the round advice "10,000 steps burns 500 calories" overshoots for nearly everyone.
- Can I use this for running steps?
- No, and the reason is the stride, not the MET. Running steps are much longer than walking steps and get longer as you speed up, so a step count from a run converts to far more distance than this tool assumes. Running also sits at MET 8 and up. Use a running calculator, or at minimum measure your running step length and treat the distance here as an undercount.
- Is anything I type saved or sent anywhere?
- No. The calculation runs in your browser. Your steps, weight and height never reach a server, aren't stored, and are gone when you close the tab. There's no account and nothing to install.
