Enter the required personal values to estimate calorie burn and treat the result as general guidance.
Inputs
The strongest pages in the library pair the live calculator with a topic guide and, where it helps, a printable reference you can reuse offline.
A fuller guide to intake planning, covering hydration, macro splits, and calorie-burn style estimates in a careful, formula-based way that stays useful without pretending to be medical advice.
A more complete guide to one-rep max estimates, pace calculations, and target heart-rate zones, written to support training decisions without overstating certainty.
A better intake-planning reference that treats hydration and macro targets as structured estimates rather than rigid prescriptions.
A more substantial performance guide for pace and heart-rate planning, designed to keep effort zones and pacing decisions practical.
Use this calculator to estimate exercise energy use from the MET value, body weight, and exercise duration you enter yourself.
The main result shows estimated calories burned, with the MET value repeated underneath so the assumption stays visible.
Calorie-burn estimates vary with technique, actual exercise intensity, and physiology. Treat the result as a planning estimate rather than an exact measurement.
Estimate basal metabolic rate from age, sex, height, and weight using the Mifflin-St Jeor equation with neutral, non-clinical presentation.
Turn a calorie target and chosen percentage split into daily protein, carbohydrate, and fat goals.
Estimate a target training heart-rate range from age and chosen intensity percentages using a standard rule-of-thumb formula.
Calculate pace per kilometre or mile from the distance and finish time you enter, with clean support for running and walking scenarios.
