## MET Calorie Formula

**Calories Burned = MET x Weight (kg) x Duration (hours)**

MET (Metabolic Equivalent of Task) measures the energy cost of an activity compared to rest (1 MET = resting).

### Common MET Values

| Activity | MET |
|---|---|
| Walking (slow) | 2.0 |
| Walking (brisk) | 3.5 |
| Jogging | 7.0 |
| Running (fast) | 9.8 |
| Cycling | 6.0 |
| Swimming | 8.0 |

计算示例

A 170 lb person jogging (MET 7.0) for 30 minutes.

  1. Weight in kg = 170 x 0.4536 = 77.1 kg
  2. Duration in hours = 30 / 60 = 0.5 hours
  3. Calories = 7.0 x 77.1 x 0.5 = 270 cal
