The answer is: A pound of flour from the Fluffy Flour Company will be the same weight as a pound of flour from another company.
In the before standard for weight and measures were created, commodities such as flour was sold using 'bags' as standard of measurement. This cause a lot of problems among buyers because many sellers put very little amount of flour inside one bag in order to obtain many profit
Because of such problems, Standard for weight and measures were invented so the sellers would not be able to cheat the buyers by less amount that they suppose to.
