Why do you need to have standard unit of measure?

Answer 1

You've run out of fresh water in the house, and you're telephoning around town to decide where to buy more.

You phone one neighborhood grocery store; they're selling certified fresh water at a cost of $36 per frublik.

Then you phone the supermarket on the next block; they're selling the same exact water for $28 per glem.

Which one do you buy ? Do you care ? Do you want to stretch your money ? Do you want the lower price ? How do you know which one is the better deal ? You have no idea how big a frublik is, or how many glems it holds. YOU CAN'T DO BUSINESS !

That goes for every manufacturer in the country, and every country in the world. Without standard units, there is no industry, no manufacturing and no trade. There are no cities, and everybody is growing their own mangos, potatoes and sheep again in their back yard.

Another example: You have a headache and you call your doctor. He wants you to take two splurgs of that pink liquid he gave you last month, and call him in the morning.

How much is a splurg ? You'd better be darn sure you know, before you put it into your body ! You'd be a lot safer, and your life expectancy might increase, if you and the doctor had a standard unit that you both agreed on. Can you think of any other examples ?

Answer 2

Standard units of measurement are needed to ensure consistency and accuracy in communication and comparison of quantities. They help to minimize errors and confusion in various fields such as science, engineering, and trade by providing a common reference point for measurement. Standard units also facilitate international collaboration and ensure that measurements can be easily understood and replicated across different regions.
