Some may get converted into muscle.

Fat is converted into units of energy and is burned up by the body. Fat does not turn into muscle, nor does muscle turn into fat.

The fat is first broken down by the body into fatty acids and glycerol, the latter of which is broken down by the liver into glucose.
Glucose helps to supply the muscles with energy and a bi-product of this energy production is carbon dioxide. This is then taken by the blood vessels to the lungs and exhaled, to be replaced by fresh oxygen.
Most of our weight loss after diet and exercise is not through sweating or any other bodily excretion or secretion, but carbon in the CO2 we breathe out.
If this sounds unlikely, then think about a mighty oak tree or redwood, and bear in mind that over 95% of a tree's weight is from carbon absorbed from the CO2 in air for the purpose of photosynthesis.

Fat can NOT be directly converted into muscle or vice-versa. One is made from Protein and the other lipids. No commonality at all.
The body does not like to burn fat. It will, without sufficient glucose in the blood, burn lean tissue (muscles/organs) first!
