Calories Burned Calculator

Your Weight

Tip: switch units if needed.

Duration (minutes)

Whole minutes are fine; you can enter decimals too.

Activity (preset MET)

Presets use typical MET values; adjust with a custom MET if you know yours.

Custom MET (optional)

If provided, custom MET overrides the preset.

Calories Burned – Quick Cheat Sheet

What’s MET? Metabolic Equivalent of Task. 1 MET ≈ resting energy cost.
Formula: kcal = MET × 3.5 × weight(kg) ÷ 200 × minutes.
Presets are typical METs; intensity, terrain, and technique can change your actual MET.
Custom MET overrides presets—use it if you have lab/device-based estimates.
Units: lbs automatically convert to kg.
Scope: This estimates gross energy cost; it does not subtract resting burn (net).

Notes & edge cases

Very high METs (>18) or very long durations can be unrealistic—verify your inputs.
Environmental factors (heat, altitude), grade, and load carriage can change MET significantly.
Device estimates (watches, treadmills) may use proprietary models; numbers won’t always match.
