Answer:
4.It is there to insure that when you buy a kilo of meat it is actually a pound. Or more importantly given the price of gas, when you buy a litre of gasoline it is actually a full litre. It is there to insure that anything that is sold by weight of volume is measured to the same standard when imported to a country.
5.Supervision of weights and measures promotes accurate measurements of goods and services to ensure that everybody gets a fair trade in the marketplace. Not so coincidentally it also is a deterrent to ensure that traders are being honest in their trade practises. Then look at the construction industry. Without constant adherence to accuracy any building/bridge or other construction would soon lose its integrity.
Explanation:
You ask a great question, one that I think does not occur to most people.
The fundamental answer is that without regular supervision of, and definitions of, weights and measures, commerce and exchange would be impossible, and there would be no market whatsoever for anything.
Imagine yourself going to a vegetable market and asking for 3 pounds of beans.You get a sack about the size of a pack of cigarettes. The next guy gives you a sack about the size of a large softball - much bigger. Both the sellers are claiming they gave 3 pounds, but without any common agreement on definitions of what pound is, you have no sales, no commerce, and no markets. Instead you would have endless, even violent, quarreling.
How about asking somebody how far ahead a state park is from the gas station where you have stopped. Somebody says: 35 miles. Thinking this might be wrong, you try the next gas station, and they say 6 miles. Would you want to live in a situation like this?
I hope your question does not mean you are afraid of public authority or standard agreements about measurements. If you are afraid, you are in very big trouble. This is not a threat, It is a statement about what the consequence would be of having no standard definitions for measurement.
