Walking Calorie Calculator

Enter weight, speed, and duration to estimate calories burned.

Calories per min ~= (MET * 3.5 * body mass_kg) / 200 Total Calories ~= Calories/min * Duration(min) Speed -> MET mapping adjusted for incline
Weight 70 kg, speed 5 km/h (MET~=3.5), 30 minutes -> ~36.75 kcal per 10 min *3 = 110.25 kcal.

How are calories estimated?

We estimate based on weight, speed (mapped to METs), duration, and optional incline. MET = metabolic equivalent of task.

What speeds correspond to METs?

Approx: 3–3.5 km/h ~= 2–2.8 METs; 4–5.5 km/h ~= 2.8–3.5 METs; 6+ km/h ~= 4.3–5+ METs. Incline raises MET slightly.

Is the estimate exact?

It is a widely used estimate, but individual burn varies with biomechanics, terrain, temperature, and fitness.

Can I enter miles?

Convert: 1 mph ~= 1.609 km/h. A miles-based version can be added if preferred.

How are calories estimated?

We estimate based on body weight, walking speed (METs), duration, and optional incline.

What are METs?

MET is metabolic equivalent. 3.5 MET ~= easy walking; 5.0+ MET ~= brisk walking. We map speed to METs.
