This calculator computes the weight loss (fat plus muscle), as well as the burned calories for more than 500 physical activities.

## How to calculate the burned calories or weight (mass) loss

The number of calories you burn depends on:

• the physical activity
• the person's body weight
• the time spent doing the activity

Multiply your body weight in kg by the MET (Metabolic equivalent) value by the time of activity, you'll get the approximate energy expent in Kcal according to the person's body weight. In this case, at a MET value, burns Kcal/kg x body weight/h.

A kg individual for minutes will burn the following:

(METs x kg body weight) x ( min/60 min) = Kcal.

is the value in METs for .

To transform the value in calories into pounds just divide the value in calories by 3500. So,

/3500 = pound = ounce = gram of mass. We can't say that it is fat because it could be also muscle.
