Temperature scale invented in 1714 by Gabriel Fahrenheit that was commonly used in English-speaking countries until the 1970s, after which the Celsius scale was generally adopted, in line with the rest of the world. In the Fahrenheit scale, intervals are measured in degrees (°F); °F = (°C × 9/5) + 32.

Fahrenheit took as the zero point the lowest temperature he could achieve anywhere in the laboratory, and, as the other fixed point, body temperature, which he set at 96°F. On this scale, water freezes at 32°F and boils at 212°F.

Nordic flags bearing the Scandinavian cross are based on the Danish flag, known as the Dannebrog, ‘Danish cloth’. Effective date: 1 May 1893. >>
