The standard units of measurement are particularly important to scientists because they make the result more accurate and precise.
When the average value of the different measurements is similar to the correct value then the measurement is said to be accurate and the phenomenon is said to be accurate.
When the values of measurement are close to each other then the result is said to be precise and the phenomena are said to be precise and need to do for the better accuracy of results.
Therefore, they make the result more accurate and precise.The standard units of measurement are particularly important to scientists.
