Question

This question is about terminology for physical quantities.

When we talk about magnitude (while talking about scalars and vectors) do we refer to just number or Number along with units?

example: If a person weighs 120 pounds, then "120" is the numerical value and "pound" is the unit.

Which is magnitude? 120? or 120 pounds?
In the book I'm using its written as

The number indicates the magnitude of the scalar quantity and is inversely proportional to the unit chosen.

This statement is wrong. Right? Its not the number alone. Its along with units.

You dont give magnitude of pounds, you give magnitude of , say mass (as here). So the magnitude is 120 pounds.
