A relevant comparison to try
Record the same route with the same device on two typical days. Keep weight and step length fixed, compare steps and duration, and treat small calorie differences as noise.

How to use this calculator
Count steps for one walking session, measure the average length of a single step and enter moving time. The tool checks the implied speed before applying the 3.8-MET level-walking reference. Use centimetres for step length even when body weight is in pounds.
Formula and methodology
Distance km = steps × one-step length cm ÷ 100,000. Speed = distance ÷ hours. For level walking at 2.8–3.4 mph: gross kcal = 3.8 × 3.5 × kg ÷ 200 × minutes.
Worked example
At 5,000 steps of 70 cm, distance is 3.5 km. Completing them in 42 minutes gives 5 km/h, within the supported pace band. For 70 kg, the estimated gross energy is 196 kcal, or 144 kcal above rest.
What the result means
Step count alone does not determine energy expenditure. This model combines a measured distance assumption with time and weight, then uses a narrow pace band rather than claiming the same calories for every step.
Limitations
Terrain, fitness, gait, speed and step-length variation affect the estimate. It excludes running, stairs and walking outside 2.8–3.4 mph. Whole-day step totals with an arbitrary duration are not suitable inputs.
Common mistakes
A stride can mean two steps. Enter one-step length, or the distance will double. Do not include seated time and pauses in the moving duration.
Frequently asked questions
Why is my walking time rejected?
Your steps and step length imply a speed outside the reference band. The tool withholds an unsupported estimate instead of assigning an arbitrary calorie value.
Is a step always worth the same calories?
No. The result depends on weight, duration and assumptions about the walking activity.
