- Two related questions — version one (one international, one Anglo-American).
- What would a graph of the Celsius temperature scale look like when plotted against the kelvin scale (Celsius on the y axis and kelvin on the x axis)? What slope would the graph have? What y intercept?
- What would a graph of the Fahrenheit temperature scale look like when plotted against the kelvin scale (Fahrenheit on the y axis and kelvin on the x axis)? What slope would the graph have? What y intercept?
- Superimpose the two graphs. Where do they intercept?

- Two related questions — version three (Anglo-American only).
- What would a graph of the Celsius temperature scale look like when plotted against the Fahrenheit scale (Celsius on the y axis and Fahrenheit on the x axis)? What slope would the graph have? What y intercept?

numerical
- The Homigrade (human scale) temperature scale was invented by the American physician Franklin E. Aspinwall in 1918. He assigned a temperature of 0 °H to the normal freezing point of water and 270 °H to the normal boiling point.
