Prefixes, metric

Larger and smaller distances may be measured with units formed by the addition of prefixes to the word meter. The important metric prefixes are listed in Table 2-2. The most important prefixes are kilo, milli, and centi. The prefix kilo means 1000 times the basic unit, no matter to which basic unit it is attached. For example, a kilodollar is 1000. The prefix milli indicates one-thousandth of the basic unit. Thus, 1 millimeter is 0.001 meter 1 mm = 0.001 m. The prefix centi means one-hundredth. A centidollar is one cent the name for this unit of money comes from the same source as the metric prefix.

Chemistry is full of calculations. Our basic goal is to help you develop the knowledge and strategies you need to solve these problems. In this chapter, you will review the Metric system and basic problem solving techniques, such as the Unit Conversion Method. Your textbook or instructor may call this problem solving method by a different name, such as the Factor-Label Method and Dimensional Analysis. Check with your instructor or textbook as to for which SI (Metric) prefixes and SI-English relationships will you be responsible. Finally, be familiar with the operation of your calculator. (A scientific calculator will be the best for chemistry purposes.) Be sure that you can correctly enter a number in scientific notation. It would also help if you set your calculator to display in scientific notation. Refer to your calculator s manual for information about your specific brand and model. Chemistry is not a spectator sport, so you will need to Practice, Practice, Practice. 

Scientific measurements range from fantastically large to incredibly small numbers, and units that are appropriate for one measurement may be entirely inappropriate for another. To avoid the creation of many different sets of units, it is common practice to vary the size of a fundamental unit by attaching a suitable prefix to it. Table 4-1 shows common metric prefixes and the multiples they indicate for any given unit of measurement. Thus a l g gs ater is 1000 meters, a microgram is 10-6 ram ana a nanosecond is Q-9...

Dimensional analysis is the method to convert a number from one unit to another using a conversion factor. Conversion factors establish a relationship of equivalence in measurements between two different units. Examples of conversion factors are tabulated in Table 3.1 (metric prefixes) and Table 3.3 (common conversion factors).
