WinThermO is a graphical, interactive, temperature conversion and display utilility. The User Interface is in the form of an attractive clipboard-mounted thermometer. When you perform a temperature conversion - from Fahrenheit to Celcius or vice versa, the scale of the thermometer automatically adjusts to the range within which the values fall, and the mercury jumps to the level of the result. Physically drag the mercury up or down, and the From and To values scroll with the movement. It also features an extensive list of Useful Temperatures arranged in categories such as Atmosphere, Earth, Human Body, Metal melting points, Stove/oven levels etc. You simply select a category, click on a topic and the thermometer scale adjusts to what needs to be shown and the mercury rises or falls to the result. This is a great feature for both reference and educational purposes - the graphical depiction of the various temperatures provides context, makes comparisons easy and aids retention.
