*Scott catalog number.
**FDC = first day cover; SS# = souvenir sheet, MS# = miniature sheet, where # = number of stamps in sheet, and the numbers in parentheses are the catalog numbers of the stamps in the sheet.

1WMD = World Meteorological Day.
2The official name was changed to "kelvin" and symbol "K" by the 13th General Conference on Weights and Measures (CGPM) in 1967.
3The official name was changed from "centigrade degree" to "Celsius degree" by the 9th General Conference on Weights and Measures (CGPM) in 1948.
4An advertisement card for China Uniform, a big telecommunication company. The thermometer has all 100°C above, and Chinese city names (likely the capital for each province) below. The cities are located from north to south (colder to hotter) when you read from left to right. The markings are actually meant to represent "100-percent-special" in each city, the service being the same in each city with no "temperature" difference. The 100°C might also imply their good and warm service. [Translation provided by Fang Wang, Colorado State University]
