Walking Pace And MET Table
The estimate assigns a MET value from pace, then adjusts it slightly for terrain and carried load. MET means metabolic equivalent. It is a standard way to compare activity intensity. These values are planning estimates based on walking entries from the Compendium of Physical Activities. Real energy use can change with fitness, stride length, wind, stops, gradients and walking surface.
| Pace | Approx Speed | Base MET Used |
|---|---|---|
| 20 min/km | 3.0 km/h | 2.5 MET |
| 18 min/km | 3.3 km/h | 2.8 MET |
| 15 min/km | 4.0 km/h | 3.0 MET |
| 13 min/km | 4.6 km/h | 3.3 MET |
| 12 min/km | 5.0 km/h | 3.5 MET |
| 11 min/km | 5.5 km/h | 4.0 MET |
| 10 min/km | 6.0 km/h | 4.8 MET |
| 9 min/km | 6.7 km/h | 5.3 MET |
| 8 min/km | 7.5 km/h | 6.3 MET |
| 7 min/km | 8.6 km/h | 7.0 MET |
Formula Method
Gross kcal: MET x 3.5 x body weight kg / 200 x minutes.
Active kcal: (MET – 1) x 3.5 x body weight kg / 200 x minutes.
Gross kcal includes resting energy during the walk. Active kcal subtracts the 1 MET resting part and is closer to the activity-only figure shown by many fitness trackers.
1 Convert the distance to kilometres and multiply by pace to get minutes.
2 Convert pace to speed and choose a base walking MET.
3 Apply terrain and carried-load adjustments without treating them as exact science.
4 Report active kcal, gross kcal, active minutes and weekly totals together.
How To Read The Result
The main figure is active calories. It estimates the energy above resting level for the walk you entered. Gross calories are also shown because many exercise science examples use the full MET formula. If a watch, phone or treadmill gives a different value, the difference may come from heart-rate data, body composition, step length, gradient, pauses or a different MET table.
The weekly line multiplies the single-walk result by your walk frequency. NHS adult activity guidance mentions at least 150 minutes of moderate intensity activity per week, or 75 minutes of vigorous activity, plus strengthening activities. A brisk walk may count when it raises breathing and heart rate. The calorie estimate does not decide whether a walk is suitable for a health condition.
Worked Walking Examples
5 km At 12 min/km
75 kg walker: about 164 active kcal on flat pavement, with a 60 minute duration.
3 km School Run
80 kg walker: a 15 min/km pace gives a gentler estimate, but weekly walks still add up.
10 km Hilly Walk
70 kg walker: hills raise the MET estimate, so the active kcal can be much higher than a flat route.
When Not To Rely On Calories Alone
Walking calories are estimates, not a medical prescription or weight-loss guarantee. They do not account for illness, injury, pregnancy, medication, heart conditions, pain, gait changes or exact body composition. Stop and seek advice if you have chest pain, fainting, severe breathlessness, new severe pain or symptoms that worry you. If you are building activity after illness or a long break, start gently and follow advice from a clinician where relevant.

FAQs
Is active kcal or gross kcal the better number?
Active kcal is usually better when you want the extra energy linked with walking. Gross kcal includes resting energy during the same minutes. Fitness apps vary, so compare like with like before deciding that one value is wrong.
Why does my watch show a different calorie burn?
A watch may use heart rate, age, sex, height, stride, recent training data or its own model. This page uses weight, pace, distance and MET values. Both are estimates, and neither should be treated as a laboratory measurement.
What pace counts as brisk walking?
For many adults, brisk walking is a pace that raises breathing and heart rate while still allowing conversation. The exact pace varies by fitness. The table gives speed bands, but perceived effort matters too.
Should I enter stones or kilograms?
Either is fine. If you choose stone, enter a decimal value such as 11.5. For the formula, the script converts the value to kilograms before estimating calories.
Do hills and bags make a big difference?
They can. Hills, rough ground, prams and packs can raise effort. The adjustment is deliberately modest because real gradients and carried loads are hard to capture from one field.
Can I use this for weight loss planning?
Use it as one planning input only. Body weight change depends on food intake, overall activity, health, sleep and many other factors. For clinical diet advice, speak with a qualified professional.
Does walking pace affect weekly activity minutes?
The minutes count is simply duration. Pace affects intensity and calorie estimate. NHS guidance focuses on activity time and intensity, not calorie burn alone.
