What are the four types of scales?

Is age an interval or ratio?
A ratio scale has the first characteristic of the interval scale (interval) but also has a meaningful zero point—which means the absence of the attribute. This enables multiplication and division on the values. Using the aforementioned definition, age is in a ratio scale.
Is weight an interval or ratio?
For example, because weight is a ratio variable, a weight of 4 grams is twice as heavy as a weight of 2 grams.
