  1. Conversion Problems 3.3

  2. Conversion Problems 3.33 • Because each country’s currency compares differently with the U.S. dollar, knowing how to convert currency units correctly is very important. Conversion problems are readily solved by a problem-solving approach called dimensional analysis.

  3. 3.3 Conversion Factors • Conversion Factors • What happens when a measurement is multiplied by a conversion factor?

  4. 3.3 Conversion Factors • A conversion factor is a ratio of equivalent measurements. • The ratios 100 cm/1 m and 1 m/100 cm are examples of conversion factors.

  5. Conversion Factors • Animation 3 • Learn how to select the proper conversion factor and how to use it.

  6. 3.3 Conversion Factors • When a measurement is multiplied by a conversion factor, the numerical value is generally changed, but the actual size of the quantity measured remains the same.

  7. 3.3 Conversion Factors • The scale of the micrograph is in nanometers. Using the relationship 109 nm = 1 m, you can write the following conversion factors.

  8. 3.3 Dimensional Analysis • Dimensional Analysis • Why is dimensional analysis useful?

  9. 3.3 Dimensional Analysis • Dimensional analysis is a way to analyze and solve problems using the units, or dimensions, of the measurements. • Dimensional analysis provides you with an alternative approach to problem solving.

  33. 3.3 Converting Between Units • Converting Complex Units • Many common measurements are expressed as a ratio of two units. If you use dimensional analysis, converting these complex units is just as easy as converting single units. It will just take multiple steps to arrive at an answer.
