Conversion Graphs
Straight line graphs can be used to convert between different units of measurement.
Drawing conversion graphs
- Conversion graphs can be constructed from tables of two different units of the same measurement.
- The table above shows several distances measured in miles and the same distance measured in kilometres.
Drawing conversion graphs 2
- To draw the conversion graph for kilometres-miles, plot these values on a graph.
- Draw a straight line from the origin that connects all of the points.
Using conversion graphs
- To use the conversion graph, draw a line from the value you want to convert to the conversion line.
- Converting 7 miles gives approximately 11 km and vice versa.
