The Celsius temperature range was originally defined by setting zero as the temperature at which water froze.

Zero degrees C was later redefined as the temperature at which ice melts. The other point at which Celsius was set — degrees Celsius — was defined as the boiling point of water. Since its definition, the Celsius scale has been redefined to peg it to Kelvin. Zero degrees Celsius is now defined as As one degree Celsius is equal to one Kelvin, boiling point of water is equal to From the midth to midth centuries, Fahrenheit was the system most widely used in English-speaking countries, while continental Europeans preferred 'The Swedish Scale'.

With the drive to standardisation and metrication from the s, Celsius became the adopted temperature scale for the EEC later EU , with the UK and Ireland converting somewhat reluctantly after joining the European community. This reluctance was partly due to human preference. For while the Celsius scale was developed for convenience, Fahrenheit's scale was based on observation and measurement. Also, whereas Fahrenheit had developed a ratio scale, Celsius had produced an interval scale.

These are very different things, as we shall explain in a future article. This may help explain why many people prefer Fahrenheit readings as rather closer to actual experience. Incidentally, while the UK's Met Office started publishing temperatures in both Celsius and Fahrenheit from and dropping use of Fahrenheit altogether from official reports in , British media persisted in using Fahrenheit in weather reports well into the 21st century.

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. In other words, take your Fahrenheit reading, subtract 32, multiply the answer by five and then divide by nine. So 66 degrees Fahrenheit minus 32 would be 34, times five makes divided by nine equals Here, you multiply your Celsius temperature by nine, divide by five and then add 32 to find the Fahrenheit reading.

To make life a little simpler, using decimals instead of fractions, you can use 1. Trying this out in action on a hot day and remembering that multiplying by 1.
