> The calories burned calculator estimates energy used during exercise from the activity’s MET value, your body weight and the duration, using the Compendium of Physical Activities.

## Inputs

- Activity
- Body weight (kg, lb, g, oz, st)
- Duration (min, h, s)

## Results

- Calories burned
- Equivalent body fat

## Formula

```
kcal = MET × 3.5 × weight (kg) ÷ 200 × minutes
```

## Explanation

A MET (metabolic equivalent) compares an activity’s energy cost with sitting quietly. Running at 10 km/h is about 10 METs.

### How to use the Calories Burned Calculator

- **Activity**
- **Body weight**
- **Duration**
- Want to work backwards? Type a value into **Calories burned** and **Duration** is calculated for you.

Results update as you type, and every field accepts the units shown in its menu.

### How it works

Multiply MET by body weight and duration with the standard conversion factor.

### Inputs explained

FieldWhat to enterActivityChoose one: Walking, 5 km/h (3.5), Walking briskly, 6.4 km/h (5.0), Cycling, moderate (8.0), Running, 8 km/h (8.3) …Body weightUnits: kg, lb, g, oz, stDurationUnits: min, h, s

### What each result means

- **Calories burned** = [Activity]×3.5×[Body weight]÷200×[Duration]
- **Equivalent body fat** = [Calories burned]÷7.7

### Example values

How the main result changes when **Duration** changes and everything else stays at the example values above:

## Worked example

Inputs — Activity: Running, 10 km/h (9.8); Body weight: 70 kg; Duration: 30 min.

Results — **Calories burned = 360 kcal**; Equivalent body fat = 47 g.

## FAQ

**Are MET estimates accurate?**
They are population averages; fitness, terrain and technique change real values.

**Do fitness trackers do better?**
Heart-rate-based trackers can be closer for steady cardio but still vary.

**What formula does the Calories Burned Calculator use?**
kcal = MET × 3.5 × weight (kg) ÷ 200 × minutes.

**Can I work backwards from the result?**
Yes. Type the result you want into Calories burned and the calculator finds the matching duration.
