Chapter 2, Problem 2.1EP
What is the main reason scientists prefer to use the metric system of measurement rather than the English system of measurement?
Expert Solution & Answer
Interpretation Introduction
Interpretation:
Scientist preference to use the metric system rather than English system of measurement has to be explained.
Concept Introduction:
Measurement is the measure of quantity, capacity, dimensions or extent of something. Mass, length, pressure, temperature, volume, time and concentration are some common type of measurements. English system and metric system are two types of measurement systems that are in use in the United States. Measurement wise both English system and metric system are precise, but Scientists prefer metric system rather than English system because. The interrelationship between the units in metric system is not that complicated as English system. Metric system is a decimal unit system in which, converting the unit from one to another is achieved by just changing the decimal point from left or to the right. Hence metric system prevails over English system.
Explanation of Solution
English system and metric system measurements are equally more precise. But English system is much complicated to use when compared to metric system. In metric system the unit conversion is very simpler. For example the inter conversion of units in metric system is easily obtained by just simply moving the decimal point from left to right or right to left. So metric system is also called the decimal unit system. Hence metric unit interrelationships are mathematically simpler. So Scientists prefer them.
