| Abstract: | Abstract The units of the Kelvin temperature scale (with an upper case K for the proper noun “Kelvin”) are incorrectly introduced in most undergraduate introductory physical geography textbooks. The internationally recognized unit of the Kelvin temperature scale is the kelvin (lower case k), abbreviated to K (upper case). However, many introductory physical geography textbooks incorrectly use units of “Kelvin,” “degrees Kelvin,” or “oK.” The errors detract from the prestige of physical geography as a natural science discipline. |
