A Matter of Degrees

Building a thermometer is a matter of precise technology—putting just the right amount of mercury into a specially designed glass tube, for instance—but determining which numbers to use on the thermometer is entirely up to the inventor. In this interactive, create your own temperature scale by choosing fixed points of your own. Then see how your scale compares with the Fahrenheit, Celsius, and Kelvin scales.—Richard Pommier Swanson
