Scales are the fishes protection and they serve the same/similar purposes as fur or hair in mammals. The fins are used for balance, propulsion/locomotion and display as are the limbs in mammals

There are many ways in which scales assist a fish. The easiest one to explain and probably the most accurate to answer your question is that the scales are smooth and provide an aerodynamic facade, which helps them swim more efficiently.
Scales protect a fish's skin from injuries and infections. They also help fish maintain buoyancy and streamline their bodies for efficient swimming. Additionally, scales can provide camouflage and aid in thermoregulation.
It tells you the weight of what you want weighed. Some digital scales have a speaker when they tell you the weight.
