What Are The Advantages Of Using The Metric System?

Fractions are almost eliminated in the metric system. Since every metric unit is a decimal value of those above and below it, most changes between units require only the moving of a decimal point. For example, to convert kilometers to meters just move the decimal point three places to the right, which automatically multiplies it by 1,000: 3.74 kilometers = 3,740 meters.    By contrast, to find the number of yards in 3.74 miles requires first knowing that there are 1,760 yards in a mile, and then multiplying that figure to arrive at 6,582.4 yards—no small job if you don't have a calculator handy. A U.S. Department of Commerce publication notes that "one authority is convinced that the U.S. Aerospace industry alone would save about \$65 million a year in engineers' time by converting entirely to metric."    At the supermarket, thrifty shoppers who compare prices will find that they need not convert pounds to ounces (16) or quarts to ounces (32) before dividing into the price to determine price per ounce. The metric weight or volume can be divided directly into the price in each case.

There is no "English Metric System."

The "metric system" is the standard system of weights and measures developed in France more than 200 years ago and now used throughout the world. It is a decimal system that uses consistent terms to indicate how units relate to each other. For example, the "meter" is the standard unit of length/distance and the "gram" is the standard unit of weight/mass. Add the prefix "kilo-" and you've multiplied the basic unit by 1,000. A kilometer is 1,000 meters and a kilogram is 1,000 grams.

The "English" system of weights and measures is the older system formerly used in the British Empire, but now superseded by the metric system — except in the United States. The English system standardized relationships between many traditional units, such as the foot, yard, and mile (for length and distance), the ounce, pound, and ton (for weight), and the (liquid) ounce, pint, and gallon (for volume). Thus the names of units are traditional and the relationships between them are arbitrary and difficult to remember. Because it is not a decimal system, the English system is more difficult to work with. While it's easy to remember that there are 1,000 meters in a kilometer, almost no one can tell you how many yards are in a mile.
