Calories Burned Walking Per KM
Walking burns roughly 30 to 60 calories per km for most adults, with body weight and pace being the two biggest variables. A 70 kg person walking at a moderate 5 km/h burns about 37 kcal per km, while a 100 kg person at a brisk pace burns closer to 60 kcal per km on the same kilometer.
That simple range hides a lot of useful detail. Knowing your exact calories burned walking per km lets you reverse-engineer almost any fitness goal — whether you want to hit a daily deficit, plan a weekend hike, or figure out how far you need to walk to burn off lunch. This guide gives you the chart, the formula, and the context to put calories per km to work.

Quick Answer: How Many Calories Per KM Walking?
Most adults burn 30 to 60 calories per kilometer walked. Here are the typical ballparks:
- Lighter adults (50–60 kg): ~26–36 kcal per km
- Average adults (70–80 kg): ~37–48 kcal per km
- Heavier adults (90–100 kg): ~48–60 kcal per km
A useful rule of thumb: calories per km ≈ body weight in kg × 0.53 at a moderate walking pace of 5 km/h. Pick up the pace to 6 km/h and that multiplier rises to about 0.6. This single shortcut gets you within a few calories of the formal MET-based formula.
Calories Per KM Chart by Body Weight
This is the table most people are searching for. It shows calories burned walking per km across body weights and three common paces.
| Body Weight | Slow (4 km/h) | Moderate (5 km/h) | Brisk (6 km/h) | Fast (6.5 km/h) |
|---|---|---|---|---|
| 50 kg | 23 cal | 27 cal | 30 cal | 33 cal |
| 60 kg | 27 cal | 32 cal | 36 cal | 39 cal |
| 70 kg | 32 cal | 37 cal | 42 cal | 46 cal |
| 80 kg | 36 cal | 42 cal | 48 cal | 52 cal |
| 90 kg | 41 cal | 48 cal | 54 cal | 59 cal |
| 100 kg | 45 cal | 53 cal | 60 cal | 65 cal |
| 110 kg | 50 cal | 58 cal | 66 cal | 72 cal |
How to read this chart: Find your weight on the left, then pick the column that matches your typical pace. The number is your estimated calories burned per km.
A few patterns stand out:
- Weight is the biggest lever. A 100 kg person burns roughly twice the calories per km of a 50 kg person at the same pace.
- Pace adds 25–40%. Going from a slow stroll to a brisk walk lifts calories per km by about a third — without adding distance.
- The math compounds. Even a 5 kcal/km bump means 50 extra calories over a 10 km walk.
For context on how this stacks up against time-based burn, see our guide on calories burned walking 1 hour and calories burned walking 30 minutes.
How the Math Works: METs Formula
Every calories-per-km estimate traces back to MET values — the Metabolic Equivalent of Task. The standard formula used by exercise scientists is:
Calories per minute = METs × 3.5 × body weight (kg) ÷ 200
To convert that into calories per km, divide by your speed in km per minute. Here are the MET values that matter for walking:
| Pace | Speed | MET Value |
|---|---|---|
| Slow stroll | 3.2 km/h | 2.8 |
| Easy walk | 4.0 km/h | 3.0 |
| Moderate walk | 5.0 km/h | 3.5 |
| Brisk walk | 6.4 km/h | 5.0 |
| Very brisk | 7.2 km/h | 6.3 |
So for a 70 kg person walking 1 km at 5 km/h (12 minutes per km):
- Calories per minute = 3.5 × 3.5 × 70 ÷ 200 = 4.29 cal/min
- Calories per km = 4.29 × 12 = ~51 cal
In practice the real-world number is closer to 37 kcal/km because the textbook MET overstates net calorie cost slightly. Most calculators (including ours) use the adjusted figures shown in the chart above. Want a full reference? See our MET Values for Walking Chart.
Walking vs Brisk Walking Per KM
Brisk walking burns more calories per km — but the difference is smaller than most people think. The reason: walking faster covers each km in less time, partially offsetting the higher intensity.
For a 70 kg person:
- Moderate (5 km/h): ~37 cal/km
- Brisk (6 km/h): ~42 cal/km
- Difference per km: roughly 5 calories, or about 12% more
What brisk walking really wins on is calories per hour. You cover more km in the same time, so the total burn climbs significantly. If your goal is total daily calorie burn, walking faster is the easiest lever. If your goal is just to walk a specific distance, pace matters less than weight.
How Incline Changes Calories Per KM
Hills change everything. Walking uphill recruits more muscle and fights gravity directly, which dramatically increases calories burned walking per km.
| Grade | Calories Per KM (70 kg, 5 km/h) | vs. Flat |
|---|---|---|
| Flat (0%) | 37 cal | Baseline |
| Gentle (3%) | 44 cal | +20% |
| Moderate (5%) | 50 cal | +35% |
| Steep (8%) | 59 cal | +60% |
| Very steep (12%) | 74 cal | +100% |
A 5% incline — about what you'd find on a moderate hiking trail or a treadmill set near the middle — pushes calories per km up by roughly a third. A steeper 10% grade can nearly double the burn versus flat ground.
This is why trail walks and hilly neighborhoods are so efficient. You burn meaningfully more calories per km than you would on a flat sidewalk, even at the same pace.
Calories Per KM at Different Distances
Calories burned walking per km scale roughly linearly with distance at the same pace. Here are total calorie burns for common walk distances at a moderate 5 km/h:
| Distance | 60 kg | 70 kg | 80 kg | 90 kg | 100 kg |
|---|---|---|---|---|---|
| 1 km | 32 cal | 37 cal | 42 cal | 48 cal | 53 cal |
| 3 km | 96 cal | 111 cal | 126 cal | 144 cal | 159 cal |
| 5 km | 160 cal | 185 cal | 210 cal | 240 cal | 265 cal |
| 7 km | 224 cal | 259 cal | 294 cal | 336 cal | 371 cal |
| 10 km | 320 cal | 370 cal | 420 cal | 480 cal | 530 cal |
A 5 km walk — roughly what 6,500 steps covers for most people — burns about 185 kcal at average weight. A full 10 km logs 320–530 kcal depending on body weight. Curious how km maps to step counts? See how many km is 6,500 steps and how many km is 7,500 steps.
How Many KM to Burn 100, 500, or 1,000 Calories
If you have a calorie target, this table shows how many km it takes to get there at a moderate pace.
| Goal | 60 kg | 70 kg | 80 kg | 90 kg | 100 kg |
|---|---|---|---|---|---|
| 100 cal | 3.1 km | 2.7 km | 2.4 km | 2.1 km | 1.9 km |
| 250 cal | 7.8 km | 6.8 km | 6.0 km | 5.2 km | 4.7 km |
| 500 cal | 15.6 km | 13.5 km | 11.9 km | 10.4 km | 9.4 km |
| 1,000 cal | 31.3 km | 27.0 km | 23.8 km | 20.8 km | 18.9 km |
A heavier person hits 500 calories in under 10 km, while a lighter person needs closer to 15 km for the same burn. To hit 1,000 calories in a single walk you're looking at a serious 19–31 km effort — easier to spread across the day or combine with brisk pace and inclines.
For longer step targets that get you into these ranges, see how many km is 12,000 steps, how many km is 13,000 steps, and how many km is 15,000 steps.
Walking vs Running: Calories Per KM
A surprising fact: running and walking burn roughly similar calories per km at the same body weight. The big difference is time — running covers each km in 5–7 minutes, walking takes 10–15.
For a 70 kg person:
- Walking (5 km/h): ~37 cal/km
- Brisk walking (6 km/h): ~42 cal/km
- Jogging (8 km/h): ~70 cal/km
- Running (10 km/h): ~80 cal/km
Running burns about twice as many calories per km as walking, but the joint impact is much higher. Brisk walking with hills closes most of that gap — and is sustainable every single day. See walking to lose weight chart for a full breakdown of weekly calorie deficits from walking alone.
Related: Calories Per Step
If you track in steps rather than km, the conversion is straightforward. Most adults take about 1,250–1,500 steps per km. Multiply that by your calories per step and you get the same answer as the per-km math.

Frequently Asked Questions
How many calories do you burn per km walking?
Most adults burn 30 to 60 calories per km walking. A 70 kg person at a moderate 5 km/h pace burns about 37 kcal per km, while a 100 kg person at a brisk pace burns close to 60 kcal per km. Body weight is the single biggest factor — heavier people burn more calories on the same kilometer.
Does walking faster burn more calories per km?
Yes, but only slightly. Brisk walking (6 km/h) burns about 10–15% more calories per km than moderate walking (5 km/h). The bigger benefit of faster walking is calories per hour — you cover more km in the same time, so total burn climbs noticeably even though per-km burn rises only a little.
How many calories per km for a woman vs a man?
There's no real gender difference in calories burned walking per km at the same body weight and pace. A 65 kg woman and a 65 kg man both burn approximately 34 kcal per km at 5 km/h. Men tend to burn more in absolute terms only because their average body weight is higher. The math is identical when you control for weight.
How many km to burn 500 calories?
Walking 10–15 km will burn 500 calories for most adults. A 100 kg person hits 500 cal in roughly 9.4 km, an 80 kg person needs about 11.9 km, and a 60 kg person needs around 15.6 km. Adding hills or picking up the pace can shorten the distance needed.
Does incline change calories per km?
Significantly. Walking up a 5% incline burns about 35% more calories per km than flat ground. A steep 10% grade can nearly double the per-km burn. Hilly routes and trail walks are one of the most efficient ways to increase calories burned walking per km without going faster or further.
Walking vs running calories per km — what's the difference?
Running burns roughly twice as many calories per km as walking at the same body weight. A 70 kg person burns about 37 cal/km walking and 80 cal/km running. Brisk walking with inclines narrows the gap considerably and is far gentler on joints, which is why most people who walk consistently end up burning more total weekly calories than sporadic runners.
Are calories per km the same on a treadmill?
Treadmill walking burns about 3–5% fewer calories per km than outdoor walking because there's no wind resistance and the belt assists slightly. Setting the treadmill to a 1% incline closely matches the calorie cost of flat outdoor walking. For accuracy, log treadmill walks with an app that uses your weight and incline data.
