Pace matters a lot for calorie burn — a brisk walk burns meaningfully more than a leisurely stroll over the same amount of time.
How it works
Multiplying a pace-specific MET value (a standard exercise-science measure of energy cost) by body weight in kilograms and duration in hours gives an estimated calorie burn.
What this does not include
This does not include individual factors like fitness level, terrain, or incline, all of which can meaningfully shift actual calorie burn above or below this population-average estimate.
How to use this calculator
- Select a walking pace, then enter body weight and duration.
A worked example
A 70 kg person walking at a moderate pace for 1 hour burns approximately 245 calories.
What the variables mean
| Variable | Meaning |
|---|---|
| Pace | Walking intensity — light, moderate, or brisk |
| Weight | Body weight, which drives total energy cost |
| Hours | Duration of the walk |
Edge cases worth knowing
Heavier bodies burn more calories at the same pace and duration — moving more mass takes more energy, so this figure scales directly with body weight.
A weight of zero makes the calculation meaningless, so the calculator declines to show a result for that input.
Frequently asked questions
What is a MET value?
Metabolic Equivalent of Task — a standardized measure where 1 MET is the energy cost of sitting quietly; an activity’s MET value expresses how many times more energy it costs compared to resting.
Why does the calorie estimate use body weight?
Heavier bodies require more energy to move the same distance, so calorie burn scales roughly with body weight for the same activity and duration.
Is this estimate accurate for everyone?
It’s a population-average estimate — individual metabolism, fitness level, and walking surface (hills versus flat ground) can all shift actual calorie burn meaningfully in either direction.
