Dimensional Analysis -Converting between different units of measured values. Conversion Factor- numerical equality between 2 units. *** Units undergo the same mathematical manipulation as numerical conversion Significant Figure -numbers within a measured value that is trusted within the uncertainty of the measurement. Tips for Unit Conversion Calculations - Ask yourself these questions 1. What is being asked for? (i.e. what units) 2. What is the data or measured value given? (i.e. original units) 3. How must the units in the measured value be converted to get to the desired units? 4. What conversion factors are needed to convert between the specific units?
