The same walk at each speed
Same weight, duration and incline; total calories.
Questions people usually ask
How does this estimate walking calories?
The tool uses a MET-based formula: calories = MET × bodyweight (kg) × duration (hours). Level-walking METs come from the 2011 Compendium of Physical Activities (3.5 at 3 mph, 4.3 at a brisk 3.5 mph), and an incline adds the ACSM walking equation's grade term.
Why does incline change calorie burn so much?
Walking uphill increases energy demand from your muscles and cardiovascular system. Higher inclines significantly increase calorie burn versus flat walking.
Should I use bodyweight in kg or pounds?
Either works. The calculator supports metric and imperial input and converts internally to kilograms for the formula.
Is this tool free and private to use?
Yes. AI Fit Hub tools are free, no-signup browser tools. Inputs stay in your browser unless you choose to share a URL.
Do these tools replace medical guidance?
No. These outputs are general fitness estimates — not medical advice.
The formula, worked through
- Formula Walking Calorie Formula
Walking calories ≈ MET × 3.5 × mass_kg × minutes / 200, with MET = 2.0 stroll / 3.5 brisk / 5.0 fast / 6.3 power walk. Apply 1 + 0.02·grade for incline.
- Formula Calories Burned Formula (MET)
Calories burned = MET × body weight (kg) × hours. METs come from the Compendium of Physical Activities; 1 MET is about 1 kcal per kg per hour.
- Formula Food-to-Exercise Conversion Formula
Food-to-exercise: minutes_to_burn = food_kcal / (MET × mass_kg × 0.0175). MET values from Ainsworth Compendium 2011. Walk 3.5, run 9.8, cycle moderate 7.5.
