The difference between them is the density.

According to the World Meteorological Organization, fog is said to have occurred when the visibility is reduced to less than 1 km by water droplets suspended in the air. For mist, there is no uniform definition at present. Different places in the world use slightly different definitions. In Hong Kong, mist is said to have formed when the visibility falls between 1 to 5 km.
