Estimate walking, cycling, running or treadmill calories from adult MET references, body weight and duration, with a measured-cadence walking step mode. MET describes an activity intensity relative to a standard resting reference. This calculator combines an activity value with weight and duration to estimate energy expenditure. It is not a direct measurement of your oxygen use or an individual prediction. Two people with the same weight doing nominally the same activity can expend different amounts of energy. Read the selected speed and terrain description instead of choosing a preset only because its activity name sounds similar.
How to use it
- 1
Enter body weight in kilograms and select an activity matching the stated speed and terrain.
- 2
Choose minutes, or walking steps with your measured steps-per-minute cadence. Custom mode needs a sourced MET.
- 3
Click Calculate result to submit the inputs. Editing fields keeps the last submitted output until you click again.
- 4
Check the worked example, units and method limits before using the result.
Formula and methodology
Gross kcal ≈ MET × 3.5 × weight kg ÷ 200 × minutes. Net above a 1-MET baseline replaces MET with max(MET − 1, 0). Walking step duration = steps ÷ measured steps per minute.
The calculator applies the displayed arithmetic to the values entered on this device. It does not silently load a local tax rate, currency conversion or commercial assumption.
Worked calculation example
At 70 kg, 30 minutes of level walking using 3.8 MET estimates 139.65 gross kcal and 102.9 kcal above a 1-MET resting baseline.
How to interpret your result
Adult MET approximation, not measured individual expenditure, weight-loss prediction or exercise prescription. Step mode requires measured walking cadence; the treadmill preset is level walking only. The examples identify the method and input basis, so the result can be checked without guessing a hidden convention.

Scenario comparison
| Scenario | What it shows |
|---|---|
| 70 kg, 30 min, 3.8 MET walking | 139.65 gross kcal. |
| 3,000 walking steps at 100 steps/min | 30 minutes before applying the selected walking MET. |
| 70 kg, 30 min, 4 MET leisure cycling | 147 gross kcal. |
Common mistakes to avoid
- Treating steps alone as a calorie measurement.
- Comparing gross calories with a device’s active-only value.
- Using a level walking preset for hills or a different treadmill workload.
Substitute the same inputs into the disclosed equation and compare with this example: At 70 kg, 30 minutes of level walking using 3.8 MET estimates 139.65 gross kcal and 102.9 kcal above a 1-MET resting baseline. Keep the method, units and source assumptions with any recorded result.

Choosing an activity or a custom MET
The presets use values from the 2024 Adult Compendium: level walking at 2.8–3.4 mph, brisk walking at 3.5–3.9 mph, leisure cycling below 10 mph, running at 5.0–5.2 mph, and level treadmill walking at 3.0–3.4 mph. Different speeds, inclines, assistance and workloads need different values. Custom mode accepts a sourced MET within the stated range; it does not infer a value from heart rate, treadmill grade or a bike’s resistance setting.
Minutes and steps are different inputs
Minute mode uses the duration actually spent at the selected intensity. Walking step mode first estimates duration using your measured cadence in steps per minute. A step count alone cannot establish calories, because cadence, stride, terrain and intensity differ. Do not use a cycling cadence or running count in this walking-only mode. If a workout includes rests or changing speeds, calculate the active sections separately rather than assigning the most intense preset to the entire session.
Gross, net and weight-loss claims
Gross energy includes resting energy that would occur during the same period. The net output subtracts a standard 1-MET baseline, which is an approximation rather than your measured resting metabolism. Exercise kcal and food-label calories use the same kilocalorie unit in ordinary discussion, but an exercise estimate is not a guaranteed dietary deficit. Do not convert the result into an assured amount of fat lost, a food allowance or a medical exercise prescription.
Privacy and browser processing
Values entered on this page are processed in the current browser session. SolvePilot does not require an account and does not receive the values entered into the calculator. Refreshing or closing the page clears the working values unless the browser itself restores a previous session. Avoid entering identifying or account information because the calculation needs summary values only.
Accuracy and verification
Accuracy depends first on input quality. Confirm definitions, scales, dates and source information before entering a value. Keep an independent record of any result used for planning because this page does not create an official statement or retain a calculation history.
Limits of this estimate

Frequently asked questions
How do I calculate kcal burned walking?＋
Choose a walking preset matching speed and terrain, enter kilograms and active minutes, then click Calculate. Check that the preset refers to level walking. Hills, loads, age and individual physiology can change expenditure, so retain the activity assumption when comparing the estimate.
Can I calculate calories from steps?＋
Only with an explicit walking-intensity choice and measured steps per minute. The calculator divides steps by cadence to estimate minutes, then applies the MET equation. It does not use a universal calories-per-step constant or claim that all step counters measure the same movement.
Does it support a treadmill?＋
The preset represents level walking at the stated speed and zero grade. It does not model incline, handrail support, curved treadmills or every running speed. Use a properly matched reference in custom mode for a different activity rather than relabeling the preset.
Why does my smartwatch give another number?＋
A device can use heart rate, personal settings or a different algorithm, and may display active rather than total energy. This page uses a visible MET assumption. Compare gross with gross or active estimates with the net output before judging a numerical difference.
Can children use the adult presets?＋
The reference used here is the adult compendium. This calculator is an educational activity estimate and does not supply pediatric or individualized clinical values. Use age-appropriate professional guidance when planning exercise or nutrition for a child or a medical condition.
