Charles Davidson, chemist and textbook author, supports the use of metric units in the US: “Why should the United States convert to the metric system? The answer is simple. The metric system is superior to the English system. Its superiority lies in the area of interrelationships between units of the same type such as volume or length. Metric unit interrelationships are less complicated than English unit interrelationships because the metric system is a decimal unit system. In the metric system, conversion from one unit size to another can be accomplished simply by moving the decimal point to the right or left an appropriate number of places. The metric system is no more precise than the English system; it is simply more convenient (1).” Do you agree or disagree with his assertion? In either case, describe your position on this matter.
