Introducing the Calories Burned Calculator — Personalised by Your Weight

ℹ️ Informational only — not medical or fitness advice. Estimates are approximate.

The new Calories Burned calculator estimates the energy you use in a workout from your own weight, your time, and the activity — not a generic chart.

What it does

• Twelve common activities with published MET values, plus a custom-MET option.
• Personalised by your body weight, the biggest factor in the formula.
• Total, per-minute, and per-hour calorie rates so you can compare workouts.
• MET-based using the ACSM formula, entirely in your browser.

Why we built it

Generic “this activity burns X calories” figures ignore the person doing it, which makes them close to meaningless. By starting from your weight and time, this calculator gives a far more useful estimate — while being upfront that all such numbers are approximations. It’s a natural companion to our daily calorie tool.
