The Travellers' Temperature Tips
Many businessmen, tourists, golfers from the USA and UK are going to travel to the countries that use SI system. The base SI unit of temperature used in science is the Kelvin but a change of 1 K is the same as 1 degree of the popular metric unit, the degree Celsius, so both units are used in parallel.
In 1742, a Swedish astronomer, Anders Celsius designed a temperature scale from 0 to 100. The lowest, cold end (0), he affixed for the temperature at which water freezes and the highest (100) for the temperature at which water boils. This scale, known as the centigrade scale became widely spread.To honour Celsius, in 1948, the centigrade was named the degree Celsius. Until the 1970, English speaking countries used the Fahrenheit temperature scale based on affixing 32 for the freezing point of water and 212 for the boiling point of water with the difference between both ends divided into 180 parts (degrees Fahrenheit).
However, due to a convenient, easy to grasp in - every - day – life, the Celsius scale gained popularity and now is commonly used in every country of the world with two prominent exceptions: USA and UK! However, the differences between magnitudes of these two units produce headaches for housewives, students, technicians, travellers on both sides of the divide. “Have I set the temperature of my oven correctly?”. “ My body temperature is 37.8 ºC. Should I go to a doctor?”. “I am travelling to Cracow... CNN reports that temperature there, at present, is – 19 ºC; how should I dress?” " We are playing golf at the President's Cup in George, South Africa. During that period, the temperature rises during day to 26 ºC...
An so on...Very often the problem is to change correctly the degrees Fahrenheit to the degrees Celsius or vice versa, especially when faced with urgency. With help comes the Internet. According to one search engine only in April this year about 50 000 people in the world turned to the Internet for help to convert either the degrees Fahrenheit to the degrees Celsius or vice versa. Oh, I wish 10% of them found my book in every coming month! And then...10% turned into buyers! (...Wacek, stop dreaming! For only these two keywords you want to get a fat salary! Please continue!). OK, then, something easy to remember during your trip:
temp. in ºC
To change to your familiar Fahrenheit degrees:
2) subtract 10% (or 1/10) of the result (eeeasy!) 3) add 32
Easy, but you need to memorize the number “32”! How to help your memory? Say, you correlate it to your age, a certain event: “when he was 32” or AD 32 crucifixion of Jesus; the possibilities are endless. I memorize: “I need to add the next higher number than the highest number of days in a month, i.e. 32”.
Remember these three steps:
ºC x 2, -10%, +32 ??? ºF (exact!!)... and... keep warm! . The algorithm of conversion can be copied and distributed freely subject to the inclusion of the author's name and the author"s website www.wacek.co.za
