To determine the percentage of fat in the body, there is a very simple method of measuring the thickness of fat on the stomach (at 10cm to the right of the navel, at the same height). Usually to measure the folds use the special device – a caliper, and the procedure is called calipatria. The caliper is in fact the conventional forceps are coated with a ruler. To replace this device it is possible in conventional calipers, or even a wrench 🙂
So, find the point on the right of the umbilicus, measure the thickness of folds in this spot (in millimeters). Then use the following table to calculate the percentage of fat in our body.
