The metric system is a decimal-based system of measurement units.
Calculations involve the simple process of moving the decimal point to the right or to the left.
Weight is actually the force with which a body is attracted toward the earth because of gravity. However, metric system use has become widespread throughout our economy. Consumers may be surprised at the number of items in everyday use that have been manufactured in metric units for some time. These items are accepted with little difficulty and include photographic equipment, automobiles, computers, pharmaceutical products, wine and distilled spirits, and soft drinks. Also, our scientific and medical communities use metric units almost exclusively.
