Calories Burned Calculator

Free calculator to estimate the number of calories burned during routine daily activities or a workout based on activity duration.

How to Use the Calories Burned Calculator

Enter body weight, activity intensity (MET), and duration to estimate calories burned during exercise.

Formula: Calories burned ~= MET * body weight (kg) * duration (hours).

Energy Expenditure Estimate

MET-based models provide practical activity-calorie approximations.

Intensity Sensitivity

Small intensity changes can shift output notably.

Goal Application

Use estimates for planning, not as exact calorie accounting.

Tracking Context

Combine with nutrition and body-weight trends for better decisions.

Uncertainty Buffer

Conservative interpretation reduces overcompensation risk.

Frequently Asked Questions

What is MET?+

MET is metabolic equivalent used to represent activity intensity.

How accurate are calorie-burn estimates?+

They are approximations and vary by physiology and execution intensity.

Does weight affect calorie burn?+

Yes, higher body mass typically increases energy expenditure for same activity.

Can heart-rate monitors differ from calculator?+

Yes, device algorithms and assumptions differ.

Should exercise calories be fully eaten back?+

Not always; planning depends on goal and estimate uncertainty.

Can duration errors affect result strongly?+

Yes, duration and intensity assumptions drive output magnitude.

Is walking MET same for all speeds?+

No, MET values vary by pace and terrain.

Can this help weight-loss planning?+

Yes, as directional estimate alongside intake tracking.

How often should activity estimates be updated?+

Update with routine, intensity, or fitness changes.

Is this a medical measurement?+

No, it is a planning approximation.
