ABSTRACT
Electrical power measurements are important quantities, which must be measured precisely. Electrical power systems are dependent upon accurate measurements for everyday operation. Today, most nations of the world use the metric system of measurement. In the United States, the National Bureau of Standards began a study in 1968 to determine the feasibility and costs of converting the nation to the metric measurement system. The United States has been one of these reluctant countries because of the complexity of actions required by a complete changeover of measurement systems. The English system of units, which uses units such as the inch, foot, and pound, has been used in the United States for many years. However, many other countries use the metric system, which has units such as kilometers, centimeters, and grams. The SI system, which was introduced in 1960, has several advantages over the English system of measurement.
