A scale is used to measure things...I see you've tagged "tornadoes" so you may be referring to the Fugita Scale--which is used to measure the damage caused by a tornado.

The scale used to identify minerals is called the Mohs scale of mineral hardness. It ranks minerals from 1 (softest) to 10 (hardest) based on their ability to scratch or be scratched by other minerals.
The most commonly used scales for Airfix models are 1/24 and 1/72. The 1/24 scale is mostly used for cars and motorcycles while the 1/72 scale is mostly used for aircraft, rockets and military vehicles.
Yes to scale out models for different things.
The HO scale is used for measuring when it comes to model trains. Originally there was the O scale, or O gauge. When train models went to an even smaller size they created the HO scale to measure them.
Models are used to explain how something works.
An Italian film "Cabiria" (1914) used scale models of mountains and volcanoes. It was a 180-minute silent black-and-white film directed by Giovanni Pastrone.

The Mohs scale helps scientists to identify the hardness of a mineral. It quantifies the scratch resistance of various minerals by ranking them from 1 (softest) to 10 (hardest).
The first motion picture to use scale models was the 22-second "A Railway Collision", filmed in 1900 by Paul's Animatograph Works. Two years later, the 14-minute French short "La Voyage Dans la Lune", aka "A Trip to the Moon" used a number of animations and scale models.

A kitchen device used to measure the weight of ingredients and other food. Kitchen scales are available in balance or spring models. A balance scale will give a more accurate reading than a spring scale. Using a scale will result in a more accurate measurement of the ingredients than by measuring it by volume. Scales are available in manual and digital models.
