Data Handling Conversion Graphs We use a conversion graph when two units have a linear relationship Metric weight in grams has a linear relationship with imperial weight in ounces: 25g = 1oz 50g = 2oz 400g = ? Data Handling Conversion Graphs Both grams and ounces can be plotted on a graph to show a diagonal line where they are equivalent. This graph can then be used to determine how many ounces there are in grams or how many grams there are in ounces. Data Handling Conversion Graphs grams Work out what will go on each axis. Decide on the division of units ounces Data Handling Conversion Graphs grams Work out a suitable scale for each axis 275 250 225 200 175 150 125 100 Plot the equivalent values and join up with a straight line 75 50 25 1 2 3 4 5 6 7 8 9 10 11 12 ounces Data Handling Conversion Graphs grams Once the diagonal line is plotted you can convert grams to ounces… …and ounces to grams 275 250 225 200 175 150 125 100 75 50 25 1 2 3 4 5 6 7 8 9 10 11 12 ounces Data Handling Conversion Graphs 275 For values larger than the scale you can multiply up for example: 16oz. = 10oz. + 6oz. This is 250g + 150g = 400g 250 225 grams 200 175 150 125 100 75 Or 2 x 8oz 50 25 1 2 3 4 5 6 7 8 9 10 11 12 ounces
