What affects walking energy?
A longer or faster walk usually uses more energy, but gradient, surface, load, and walking economy also matter. Two people covering the same route can have different expenditure.
A speed-based MET estimate
Your entered speed selects the nearest published level-walking speed interval in the 2024 Adult Compendium, with equal-distance ties choosing the faster interval. Reference values range from 2.3 to 8.5 MET; the tool accepts speeds from 1–8 km/h. This lookup is not continuous interpolation.
How to use this calculator
- 1Choose metric or imperial units and enter body weight.
- 2Enter average walking speed in km/h or mph and the duration of the walk.
- 3Calculate estimated distance and gross versus net active energy.
Understanding your result
Gross calories include the approximate resting energy you would have used during that time. Net active calories remove a standard resting estimate. Choose the relevant figure before comparing with a watch or a calorie budget.
Assumptions & limitations
- This tool does not model hills, treadmills with incline, weighted packs, or unusual walking conditions.
- MET values are population references, and the standard resting baseline does not fit everyone.
Frequently asked questions
Should I include time spent stopped?+
Use walking time where possible. The model applies the entered speed and intensity throughout the duration, so counting long stationary breaks can overestimate energy and distance.
Does uphill walking burn the same amount?+
No. Incline usually increases energy demand, but this calculator does not include gradient and can underestimate a hilly walk.
Why can a small pace change move calories suddenly?+
The tool selects from discrete MET speed bands. Crossing a band boundary changes the representative value; real physiology changes more continuously.
Should I eat back the estimated calories?+
That depends on your overall plan. If your TDEE activity level already includes the walk, adding it again can double-count the same activity.
