Since you have posted multiple questions and we can answer one question. So, answered the first question.

By using units in measurement we specify the amount of the thing. If we do not use units then we can not understand how much the amount stands.

If I say go to the market and buy 5 oil. Then what can you do? You cannot buy 5 oil. But you can buy 5 litres of oil.

So, here the amount is 5 litres, where the litre is the unit. Hence units are so important in measurement.
