In 1790, the French National Assembly called upon the Academy of Science to design a standard decimal based system of units (The Metric System, , 2 March). The metric system is now used in all scientific measurement. The metric system is organized very well. Volume is based off of liters, mass is based off of grams, and distance is based off of meters. Certain prefixes correspond to certain powers of 10. For example, to measure mass, 1 kilogram is 10 3 grams. In the same respect, to measure distance, 1 nanometer is 10 -9 meters. The metric system has some very positive attributes. Firstly, it is easy to use. As long as you know which prefixes correspond to the conversion rate, it is very easy to do conversions. Second, the metric system’s conversions lead to exact answers. Instead using constants which
