Matter, Measurement, and Problem Solving Dimensional Analysis

Has several names ◦ Unit Conversions ◦ Unit factor ◦ Factor label ◦ Conversion factor method Using units to guide through problem solving Use to convert between measurement systems (English to metric) or within same system (Kg  g  cg)

Basic Steps of Dimensional Analysis 1. Identify what’s given 1.Property, system of units, units 2. Identify what’s asked for 1.Property system, units 1.Height in inches to meters? 2.Weight in grams to pounds? 3. Plan path 1.Given to asked for 2.Use given and known conversion factors 3.Units should cancel to get to next unit in path
