What the result means

Estimated calories burned answers the page's main calories burned question. MET-based exercise energy estimate rounded to whole kcal for display. Treat the result as educational context, then read the limitations and assumptions before discussing it with a professional. Use estimated burn rate, MET value used, and activity description to explain why estimated calories burned moved when an input changed. Record the inputs you used and verify any health concern with a qualified professional.

Formula

Calories burned are estimated with kcal/min = MET x 3.5 x body weight in kg / 200, then multiplied by duration in minutes. Key assumptions: This calculator is for adult educational estimates only and is not medical, exercise, or weight-loss advice. MET values are standardized approximations and may differ from measured energy expenditure. Actual calories burned vary with fitness, body composition, movement economy, terrain, environment, and measurement method.

FAQ

How is estimated calories burned calculated here?

Calories burned are estimated with kcal/min = MET x 3.5 x body weight in kg / 200, then multiplied by duration in minutes. The first assumption to check is: This calculator is for adult educational estimates only and is not medical, exercise, or weight-loss advice.

What does Estimated calories burned mean for calories burned?

Treat the result as educational context, then read the limitations and assumptions before discussing it with a professional. Secondary values such as estimated burn rate, MET value used, and activity description are there to explain the primary answer, not to replace it.

What should I enter for Weight?

Use kilograms when weight unit is kg, or pounds when weight unit is lb. Choose the mode or method first because it can change which formula is applied, keep units consistent with the labels shown in the form, and stay within the documented minimum and maximum ranges.

How does Weight unit change estimated calories burned?

Choose kilograms or pounds. Changing it can alter estimated calories burned because the formula uses the submitted inputs together. Also compare measurement method, formula population, age range, units, sex or activity assumptions, and clinical context.

Why does the calories burned example show 140 for estimated calories burned?

The default inputs produce 140 for estimated calories burned. Treat that as a format and scale check, then replace every default value with your own inputs.

Can the calories burned result diagnose or prescribe anything?

No. Use it as educational context only. Health formulas can depend on population, measurement method, age range, and clinical context.
