Ratio Scale
The ratio scale of measurement is a type of measurement scale. It is
characterized by equal intervals between scale units and a minimum scale value of zero.
The weight of an object would be an example of a ratio scale. Units
along the weight scale are equal to one another, and the minimum value is
zero.
Weight scales have a minimum value of zero because
objects at rest can be weightless, but they cannot have negative weight.
