Using the calories burned calculator below, you just need to fill some data and get the value of calories burned in Kcal.

## How to calculate calories (burned)

The number of calories you burn while exercising is dependent on:

- the exercise you do
- your weight
- the time spent doing the activity

By multiplying the body weight in kg by the MET ^{(*)} value and duration of activity, you can estimate the energy expenditure in Kcal specific to a persons body weight. In this example, rollerblading (maximal effort) at a 14 MET value, burns 14 Kcal/kg x body weight/h.

A 70 kg individual rollerblading (maximal effort) for 20 minutes expends the following:

(14 METs x 70 kg body weight) x (20 min/60 min) = 326.7 Kcal.

14 is the value in METs for rollerblading (maximal effort).

(*) MET - Metabolic equivalent
