Calories Burned Walking at a moderate pace (3 mph) at 55 kg — 182 kcal per Hour
Walking at a moderate pace (3 mph) at 55 kg (110-132 lb) burns about 182 kcal per hour. That figure comes from the activity's MET value of 3.3 in the 2011 Compendium of Physical Activities, multiplied by body weight: 3.3 x 55 kg x 1 hour = 182 kcal. This page works the numbers out in full - for 15, 30, 45, 60 and 90 minutes, across all four weight bands, and against four comparable activities at the same weight - so you can plan sessions with real figures instead of guessing.
At 3 mph (4.8 km/h) this is the everyday purposeful walking pace — the speed you walk when you are going somewhere, not strolling. You cover about 4.8 km in an hour, or a mile in 20 minutes, and you can still talk comfortably, though you will notice your breathing deepen slightly. It is the classic threshold pace: brisk enough to count as moderate exercise, easy enough to hold for an hour.
Moderate walking suits almost everyone: commuters, dog walkers, lunch-break walkers, and anyone building a daily activity habit. The headline number to remember is 182 kcal per hour at 55 kg, or about 91 kcal for a 30-minute walk. Everything below is an estimate: MET values are population averages, and your own burn will vary with fitness, technique and conditions. That does not make the numbers useless — it makes them a planning tool, and a good one, as long as you treat them as approximate.
Calculate your own numbers
Use the calorie calculator to work out your own burn for walking at a moderate pace (3 mph) at your exact weight and session length. Enter your weight, pick the activity and set the duration, and the tool applies the same MET formula shown below. You can also try the step calorie calculator to turn your daily step count into an energy figure.

The formula, shown and cited
The standard way to estimate the energy cost of an activity is the MET formula from the Compendium of Physical Activities (Ainsworth et al., Medicine & Science in Sports & Exercise, 2011; 43(8): 1575-1581):
Calories (kcal) = MET x body weight (kg) x duration (hours)
One MET is the energy you use sitting quietly at rest - about 1 kcal per kilogram of body weight per hour. An activity rated at 3.3 METs therefore uses 3.3 times as much energy as resting. The Compendium's MET values come from published studies that measured oxygen use during each activity, so they are measured averages, not guesses. The value used here, 3.3, is the one recorded for walking at a moderate pace (3 mph) in the FitCalc activity data.
Worked through for this page:
- MET for walking at a moderate pace (3 mph): 3.3
- Body weight: 55 kg (the midpoint of the 50-60 kg band, 110-132 lb)
- Duration: 1 hour
- Calculation: 3.3 x 55 x 1 = 182 kcal
For a 30-minute session the same calculation is 3.3 x 55 x 0.5 = 91 kcal. Nothing else is hidden in the maths - if your weight or duration changes, only those two numbers change.
Your numbers at 55 kg
| Duration | Calculation | Calories burned |
|---|---|---|
| 15 minutes | 3.3 x 55 x 0.25 | 45 kcal |
| 30 minutes | 3.3 x 55 x 0.5 | 91 kcal |
| 45 minutes | 3.3 x 55 x 0.75 | 136 kcal |
| 60 minutes | 3.3 x 55 x 1 | 182 kcal |
| 90 minutes | 3.3 x 55 x 1.5 | 272 kcal |
That is about 3.0 kcal per minute of walking at a moderate pace (3 mph) at this weight. A short session still counts: even 15 minutes burns 45 kcal, and three 15-minute sessions across a day add up to the same 136 kcal as one 45-minute session.
How the burn changes with body weight
The MET value stays the same - it describes the activity, not the person - but the calorie total scales with weight, because a heavier body costs more energy to move:
| Body weight | Calories per hour | Calories per 30 minutes |
|---|---|---|
| 55 kg | 182 kcal | 91 kcal |
| 65 kg | 214 kcal | 107 kcal |
| 75 kg | 248 kcal | 124 kcal |
| 85 kg | 280 kcal | 140 kcal |
Two people doing the same activity for the same time can therefore burn quite different amounts, and that is expected - it is physics, not a mistake in the formula. If your weight sits between two rows, your figure sits between the two values.
How walking at a moderate pace (3 mph) compares
Here is walking at a moderate pace (3 mph) against four other activities at the same 55 kg, all using the same MET formula:
| Activity | MET | Calories per hour at 55 kg |
|---|---|---|
| walking at a moderate pace (3 mph) | 3.3 | 182 kcal |
| walking slowly (2 mph) | 2.8 | 154 kcal |
| walking briskly (4 mph) | 5 | 275 kcal |
| walking the dog | 3 | 165 kcal |
| Nordic walking | 4.3 | 236 kcal |
Use this table to choose, not to judge. A higher number means a harder session, not a better one: the activity you enjoy and repeat three times a week beats the activity that burns more per hour but that you quit after a fortnight. Mixing intensities across the week - one harder session, two easier ones - is usually more sustainable than doing the hardest activity every time.
Fitting walking at a moderate pace (3 mph) into your week
| Sessions per week | 30 minutes each | 60 minutes each |
|---|---|---|
| 2 sessions | 182 kcal | 364 kcal |
| 3 sessions | 273 kcal | 546 kcal |
| 5 sessions | 455 kcal | 910 kcal |
At 3.3 METs, moderate walking is moderate-intensity activity, so every minute counts in full toward the widely used adult target of 150 minutes of moderate activity a week. Five 30-minute walks a week hit that target exactly and burn about 455 kcal a week at 55 kg. If five days is too much to start with, three 30-minute walks still give you 90 minutes — more than half the target — and you can add the rest as shorter 10-minute walks across the day, which count just the same.
How to use the result
Walk heel to toe, keep your shoulders relaxed and let your arms swing — pumping your arms gently adds a little to the effort and keeps your rhythm steady. Build duration before speed: get comfortable with 30 minutes a day, then stretch some walks to 45 or 60 minutes. The commute is the easiest place to find the time — get off the bus a stop early, or park further away. If you use a fitness tracker, check your pace rather than just your steps: holding close to 3 mph is what makes the walk moderate, and drifting down to a stroll drops the burn noticeably. In hot weather, carry water and walk in the shade where you can; in cold weather, warm up for the first five minutes at a slower pace. Use the numbers on this page to set realistic expectations rather than to chase a daily total. If you are tracking food as well, add the session's calories to your total daily energy expenditure for that day, and remember that the figure is an estimate with roughly 10-20% uncertainty. Do not eat back every calorie the calculator shows: activity trackers and MET estimates both tend to overstate slightly, and a small margin keeps a weight-loss plan on track. If you are aiming to lose weight, keep the deficit modest - 300-500 kcal a day is a common, sustainable range - and keep your total intake above the safety floors of 1,200 kcal a day for women and 1,500 kcal a day for men unless a healthcare professional advises otherwise.
What the number does NOT tell you
The MET formula is honest about what it measures and silent about the rest. It assumes steady walking on level ground at 3 mph, so it does not account for hills, stops, carrying bags, or walking into a headwind — all of which change the real figure. It does not account for your fitness level: a fit person burns slightly fewer calories doing the same walk than an unfit person, because their body is more efficient. It does not account for body composition, and it says nothing about strength, flexibility or balance gained. It also cannot tell you whether walking is safe for you: if you have a heart condition, joint problems, breathing difficulties or any other health concern, check with a healthcare professional before starting a new activity routine. Use the calorie figure as a planning estimate, and judge the walking by how you feel doing it and whether you keep doing it.
Frequently asked questions
How many calories do I burn walking at a moderate pace for 30 minutes at 55 kg?
About 91 kcal. The maths is 3.3 METs x 55 kg x 0.5 hours = 91 kcal. That is an estimate from the Compendium average — your real burn depends on your fitness, your exact pace and the terrain. If you weigh more or less than 55 kg, use the weight table above to read your own figure.
Is 3 mph actually brisk walking?
It is the lower edge of brisk. The Compendium rates walking at 3 mph as moderate pace at 3.3 METs, while brisk walking at 4 mph is rated 5.0 METs. At 3 mph you can talk comfortably and your breathing is only slightly raised; at 4 mph you are breathing noticeably harder. Both count as moderate activity, but 4 mph burns about 50% more per hour at the same weight.
How many calories do I burn walking at a moderate pace per mile?
About 60 kcal per mile at 55 kg. A mile at 3 mph takes 20 minutes, so the maths is 3.3 METs x 55 kg x one-third of an hour. Per mile is a useful way to compare paces: faster walking burns more per mile as well as per hour, because the MET value rises with speed.
How does walking at a moderate pace compare with walking slowly?
At 55 kg, a moderate pace burns about 182 kcal per hour against 154 kcal for slow walking at 2 mph — roughly 18% more. The difference is small per minute, but over a 30-minute daily walk it adds up to about 14 kcal extra a day, or over 98 kcal a week.
Can walking at a moderate pace help with weight loss?
It can help, but only as part of an overall calorie deficit. At 55 kg, an hour burns about 182 kcal — a useful contribution, roughly the energy in a modest meal — but weight loss still comes from the total balance of food and activity across the week, not from one walk. Aim for a gradual loss of 0.5-1% of body weight per week, and never drop below 1,200 kcal a day (women) or 1,500 kcal a day (men) without medical supervision.
Estimates only, not medical advice. Minimum safe intakes: 1,200 kcal/day women, 1,500 kcal/day men - consult a healthcare professional before a very-low-calorie diet.
