Scales are used for weighing things. To use a scale, the thing which needs tp be weighed is put on one side of the scale. Then, weigh stones are put on the other side. Once the scale balances (that is the indicator between the two scales is in the middle), the correct weigh was chosen.

There are also modern scales, where the item is simply put on the scale. Its weight can then be read from an electronic or analogue display.


Scales is also the name of some protective plates some animals (eg. some fish) have. These plates serve as a protection measure.


When used as a verb, to scale means to change the size of a thing, without changing the aspect ratio. A photo can be scaled by multiplying length and width by 2. The resulting photo would then be 4 times as big as the original.
