you have to use that measurement cause if you dont people cant make cars
There is a great deal of importance in using standard units in every day life. Having a standard unit of measurement ensures that everyone can recreate the same exact amount of material measured, regardless of whether or not they all use the same tool to measure.
No 5 tons equals 10,000 pounds.so 5 tons is greater
Standard measurements are rather like the standard meanings of the words that you and I are using to communicate with each other. If a word has a standard meaning, then when I use that word you will know what I mean. If I use a standard measurement, then I can tell other people what I have measured and they will know what the measurement means.
Because it is easy to convert
Standard measurements make it easier for everyone to know what that measurement means. The metric system, which is the standard system used by scientists, is specifically designed to be easy to use. The English system is much more complicated, mathematically.
easy to understand any one
A collection of data by the accurate observation of an object or process using a standard unit. Good enough?
The "z-score" is derived by subtracting the population mean from the measurement and dividing by the population standard deviation. It measures how many standard deviations the measurement is above or below the mean. If the population mean and standard deviation are unknown the "t-distribution" can be used instead using the sample mean and sample deviation.
It's not "superior" ... but it is the agreed on system for almost all the world - thus it's advantage is consistency.
to make the same type of measurement around world so that there is a universal when measuring certain substances.
Using a cup with a standard measurement of 250 mL (mililitres), then there are 4 cups in 1 L (litre).
So that when you discuss the measurement with other people,they'll know what you're talking about.
