Temperature width is deeply momentous to a in one piece scope of areas and activities: science, experimental research, manufacturing, medical specialty and move about. Many European, Asian and African community and tourists oftentimes motion to the USA and UK. These countries have not adopted the use of the redbrick metric linear unit set-up of measurement i.e. the SI policy.
The recognised basis SI part of heat is the Kelvin. A rework of 1K is the identical as 1 degree Celsius. As the degree Celsius is a convenient, trouble-free to embrace in all - day - duration metrical unit, as a consequence both units are utilized in symmetrical. The Kelvin is used by scientists and engineers and the point Celsius by all and sundry else comprehensive. There are however, two striking exceptions: the USA and UK who unremarkably use the Fahrenheit mount.
Daniel, Gabriel Fahrenheit, a German scientist was foaled in 1686 in Gdansk, Poland. The concept of the measuring system for measure heat changes is certified to Galileo. Fahrenheit is particular for inventing the alcoholic beverage and atomic number 80 thermometers. His fundamental quantity level is based on affixing 32º for liquescent element of ice and 212º for the vapor component of liquid lower than mean region nervous tension. The interlude concerning two basifixed points is mortal forked into 180 isothermal environs (the degrees Fahrenheit). The Fahrenheit clamber was commonly in use by English muttering countries up until 1970.
Travelers to the USA and UK are recurrently janus-faced beside the eccentricity of how to efficiently soul the temperature in the amount Fahrenheit to the fundamental measure uttered in the degrees Celsius minus fashioning a wrong step and with a ample calculation.
The transformation way "Fahrenheit to Celsius" is:
ºC = 5/9 (ºF - 32º); read:
"In dictation to formulate the heat in the degrees Celsius, I stipulation to undo 5 by 9 and the upshot compute by the fundamental quantity in Fahrenheit lowered by 32º".
Quite awkward, isn't it?
A substantially simpler way to recollect and easier blueprint to do mentally is to hit the books the cardinal shadowing steps:
ºF→→→ºC : "Subtract 32, part by 2, add 10% ( or 1/10) of the ending and add 1% of the total".
Let us see how it works:
E.g. 1: 98 ºF (your middle-of-the-road thing physical property) →→→66 →→→33 →→→36.3 →→→36.7 ºC (rounded off to one denary function).
E.g. 2: 102 ºF (your mathematical article fundamental measure) →→→70→→→35→→→38.5→→→38.9 ºC
(High, pay a look in to the doctor!).
E.g. 3: 68 ºF (pleasant, energizing exterior fundamental quantity)→→→36→→→18→→→19.8→→→20 ºC
If you in a goodish mood, hum these iv stepladder up to that time the travel: "su-di-a-a", "su-di-a-a", "su-di-a-a"...!
Have a pleasant lose your footing and support warm!

PS.: Have you read my earlier article: "The Travelers Temperature Tips"?
If so, you will be able to find the statement to the subsequent puzzle:
FORGETFULNESS
A educatee determination a difficulty on transportation of warmth saved a exact heat move. However, he given the statement without a component. As it turned out, it did not situation whether he gave the physical property in the degrees Fahrenheit or the degrees Celsius. The reply remained the same. What temperature was it?
