![]() ![]() Indeed it became the fashion to use Celsius when describing extreme winter conditions and Fahrenheit for heat waves - a nice example of double standards in action. Incidentally, while the UK's Met Office started publishing temperatures in both Celsius and Fahrenheit from 1962 and dropping use of Fahrenheit altogether from official reports in 1970, British media persisted in using Fahrenheit in weather reports well into the 21st century. On the Fahrenheit scale, these respectively measure at about 52☏ and 95☏, with the latter traditionally taken as license for red top tabloids to start running 48 point headlines containing words like 'Phew', 'Flaming' and 'Scorcher'. In Celsius, a chilly day at 11☌ does not seem greatly different from a really hot one at 35☌. This may help explain why many people prefer Fahrenheit readings as rather closer to actual experience. These are very different things, as we shall explain in a future article. Also, whereas Fahrenheit had developed a ratio scale, Celsius had produced an interval scale. For while the Celsius scale was developed for convenience, Fahrenheit's scale was based on observation and measurement. This reluctance was partly due to human preference. This is because Celsius and Fahrenheit are relative scales. ![]() There is no degree using the Kelvin scale. Remember to report Celsius and Fahrenheit values in degrees. ![]() Metrication from the 1950s, Celsius became the adopted temperature scale for the EEC (later EU), with the UK and Ireland converting (somewhat reluctantly) after joining the European community. Celsius to Kelvin: K C + 273 (or K C + 271.15 to be more precise) Fahrenheit to Celsius: C (F - 32)/1.80. Fahrenheit and celsius temperature conversionįrom the mid-18th to mid-20th centuries, Fahrenheit was the system most widely used in English-speaking countries, while continental Europeans preferred 'The Swedish Scale'. ![]()
