Convert your daily step count into calories and kilojoules burned, based on your body weight, height and walking pace.
Steps alone don't burn a fixed number of calories — the total depends on how far each step carries you (driven by your height) and how hard your body is working (driven by your pace and body weight). This calculator first works out your stride length from your height, multiplies it by your step count to get distance walked, then uses a MET (Metabolic Equivalent of Task) value for your chosen pace to work out how long that distance takes and how many calories that effort burns. As a reference point, a 70 kg adult who is 175 cm tall walking 8,000 steps at a brisk pace burns roughly 353 kcal (1,476 kJ).

Steps aren't a direct calorie unit — they're a proxy for distance, and distance combined with pace gives you the time spent moving, which the calorie formula actually needs. This calculator works through four steps: first it estimates how far each stride carries you using your height, then multiplies that by your step count to get total distance, then divides distance by your chosen pace to get how long the walk would take, and finally applies the MET value for that pace to convert your weight and time into calories.
8,000 steps is a common daily step target and roughly 6.1 km for someone 170 cm tall. The table below holds height (170 cm) and pace (brisk, 4.8 MET, 6.0 km/h) constant and varies only body weight, so you can see how much weight alone changes the result.
| Body Weight | Calories Burned | Kilojoules |
|---|---|---|
| 60 kg | 294 kcal | 1,229 kJ |
| 70 kg | 343 kcal | 1,434 kJ |
| 80 kg | 392 kcal | 1,639 kJ |
| 90 kg | 441 kcal | 1,844 kJ |
| 100 kg | 490 kcal | 2,049 kJ |
10,000 steps — about 7.65 km at 170 cm — is the most commonly cited daily step goal, though it originated as a marketing figure for an early pedometer rather than a specific health recommendation. Using the same 170 cm height and brisk pace as above:
| Body Weight | Calories Burned | Kilojoules |
|---|---|---|
| 60 kg | 367 kcal | 1,537 kJ |
| 70 kg | 428 kcal | 1,792 kJ |
| 80 kg | 490 kcal | 2,049 kJ |
| 90 kg | 551 kcal | 2,305 kJ |
| 100 kg | 612 kcal | 2,561 kJ |
Daily step totals bounce around — some days 4,000, others 14,000 — which makes day-to-day calorie totals hard to compare. Calories per 1,000 steps strips that variability out: it's the calorie cost of a fixed unit of walking, so you can compare effort across different days or different people on equal footing, then scale it up by however many thousands of steps you actually walked. The table below uses a brisk pace (4.8 MET, 6.0 km/h) and a 170 cm height.
| Body Weight | Calories per 1,000 Steps | Kilojoules per 1,000 Steps |
|---|---|---|
| 60 kg | 36.7 kcal | 154 kJ |
| 70 kg | 42.8 kcal | 179 kJ |
| 80 kg | 49.0 kcal | 205 kJ |
| 90 kg | 55.1 kcal | 230 kJ |
| 100 kg | 61.2 kcal | 256 kJ |
This calculator is built for walking. It uses a stride-length ratio (height × 0.45) and MET values that only apply to walking paces — from an easy stroll up to speed walking. Running uses a different stride mechanic (a longer, more airborne stride relative to height) and much higher MET values, typically starting around 8 MET for an easy jog and climbing past 12 MET for fast running. If your daily step count is a mix of walking and running, don't run the running portion through this walking calculator — the calorie total will be understated. Instead, work out the walking and running portions separately, using the running pace's own MET value and stride assumption for the running distance.
Height feeds directly into stride length, which is the bridge between "steps" and "distance" in this calculator. A taller person's legs cover more ground per step, so the same step count adds up to a longer walk — and a longer walk at the same pace takes more time, which is what the calorie formula multiplies against.
At 8,000 steps and 70 kg, a 170 cm walker burns about 343 kcal while a 175 cm walker burns about 353 kcal at the same brisk pace — roughly a 3% difference from a 5 cm height gap. The effect is small per centimetre but adds up over a full day of walking.
Because your step count and height fix the distance you cover, it's tempting to assume the calorie total is fixed too. It isn't, because calories depend on the ratio of MET to speed, not on distance alone — walking harder raises the MET value faster than it cuts the time spent walking. For a 70 kg, 175 cm walker covering exactly 8,000 steps, here's how the pace preset alone changes the outcome:
| Pace | Speed | Duration | Calories |
|---|---|---|---|
| Easy stroll | 3.2 km/h | ~118 min | 317 kcal |
| Slow walk | 3.9 km/h | ~97 min | 317 kcal |
| Comfortable walk | 4.0 km/h | ~95 min | 331 kcal |
| Moderate walk | 5.5 km/h | ~69 min | 305 kcal |
| Brisk walk | 6.0 km/h | ~63 min | 353 kcal |
| Power walk | 6.8 km/h | ~56 min | 357 kcal |
| Very fast walk | 7.6 km/h | ~50 min | 406 kcal |
| Speed walking | 8.4 km/h | ~45 min | 446 kcal |
Notice that moderate walk (305 kcal) actually burns fewer calories than the slower comfortable walk (331 kcal) for the same 8,000 steps. That's not a typo — it falls directly out of the MET and speed figures in the Compendium of Physical Activities, where the moderate-walk preset happens to have a lower MET-to-speed ratio than the comfortable-walk preset. It's a reminder that "faster preset name" doesn't always mean "higher calorie burn" — the actual MET and speed numbers decide it.
Australian food labels report energy in kilojoules, not calories, so this calculator shows both: multiply kcal by 4.184 to get kJ. The Australian Government's physical activity guidelines recommend adults accumulate 150–300 minutes of moderate-intensity activity (or 75–150 minutes of vigorous activity) per week — walking at a brisk pace or faster comfortably counts toward that moderate-intensity target. Step counting is a simple, device-free way to track progress toward those minutes, even though the guidelines themselves are framed in time rather than steps.
How many calories does 8,000 steps burn?
For a 70 kg adult around 170–175 cm tall walking at a brisk pace (4.8 MET, about 6 km/h), 8,000 steps burns roughly 340–353 kcal depending on exact height. Using our reference figures, a 170 cm walker burns about 343 kcal (1,434 kJ) and a 175 cm walker burns about 353 kcal (1,476 kJ). Lighter walkers burn less and heavier walkers burn more — see the weight table above for the full range from 294 kcal at 60 kg to 490 kcal at 100 kg.
How many calories does 10,000 steps burn?
At the same brisk pace and a 170 cm height, 10,000 steps burns about 428 kcal for a 70 kg adult, ranging from roughly 367 kcal at 60 kg up to 612 kcal at 100 kg. Because 10,000 steps covers 25% more distance than 8,000 steps at the same stride length, the calorie total scales up by roughly the same proportion.
Does height affect the calorie estimate?
Yes. Height determines stride length in this calculator (stride = height in metres × 0.45), so a taller person covers more distance in the same number of steps and therefore burns slightly more calories. For example, at 8,000 steps and 70 kg, a 170 cm walker burns about 343 kcal while a 175 cm walker burns about 353 kcal — roughly a 3% difference for a 5 cm height gap.
Should I count running steps the same way?
No. This calculator assumes a walking stride and walking MET values. Running strides are longer relative to height and running MET values are considerably higher (often 8–12+ MET depending on speed) than any walking pace listed here. If your daily step count is a mix of walking and running, treat the running steps separately using running-specific MET values rather than the walking presets above.
Why does walking pace change the calorie total if I take the same number of steps?
Because your step count and height fix the distance you cover, but not how hard you work to cover it. Faster paces use higher MET values, and calories scale with the MET-to-speed ratio, not with distance alone. Interestingly this ratio doesn't rise in a straight line across the presets — for a fixed 8,000 steps at 70 kg, a moderate walk (3.8 MET, 5.5 km/h) burns slightly fewer calories (~305 kcal) than a slower comfortable walk (3.0 MET, 4.0 km/h, ~331 kcal), simply because the MET-to-speed ratio dips at that point in the Compendium data.
What is "calories per 1,000 steps" and why use it?
It's the calorie burn scaled to a fixed 1,000-step block, which strips out the effect of how many total steps you happened to take on a given day. It's a more stable way to compare effort across different days or different people, since someone who does 6,000 steps and someone who does 12,000 steps can still be compared fairly on a per-1,000-step basis. At a brisk pace and 170 cm height, this ranges from about 36.7 kcal per 1,000 steps at 60 kg to about 61.2 kcal at 100 kg.
How accurate is a steps-to-calories estimate?
It's a reasonable estimate, not a precise measurement. The formula relies on an average stride-length ratio (0.45 × height) and standardised MET values, so it doesn't account for individual stride variation, terrain, incline, or fitness level. Treat the output as a guide within roughly ±15–20%, similar to other MET-based calorie calculators.
Does a fitness tracker's calorie count match this calculator?
Not exactly. Wearables use accelerometer data, heart rate, and proprietary algorithms that vary between devices and brands, while this calculator uses a fixed, public formula. Expect the two figures to be in the same ballpark but not identical — both are estimates, so use them to track trends rather than compare them number-for-number.
