What is importance of measurement?
Also measuring certain things correctly is very necessary including distance, time, and accuracy. We can really know the universe around us by measuring such occurrences or, in other words, by taking such measurements. Measurements may also enable us to make decisions on the basis of the measurement result.
What is called measurement?
Measurement is the basic concept in the study of Mathematics and Science. Measurement quantifies the characteristics of an object or event, which we can compare with other things or events.
