What is ratio scale with example?

This is a unique feature of ratio scale. For example, the temperature outside is 0-degree Celsius. 0 degree doesn’t mean it’s not hot or cold, it is a value.
Is weight nominal ordinal interval or ratio?
4. Nominal Ordinal Interval Ratio. Weight is measured on the ratio scale.
