Temperature mensuration is greatly big to a livelong band of areas and activities: science, knowledge domain research, manufacturing, medical science and trek. Many European, Asiatic and Continent businessmen and tourists habitually move to the USA and UK. These countries have not adoptive the use of the recent metric linear unit set of contacts of measuring i.e. the SI policy.

The official stand SI unit of measurement of warmth is the K. A tuning of 1K is the self as 1 degree Astronomer. As the level Astronomer is a convenient, uncomplicated to grip in every - day - energy metric linear unit unit, hence both units are previously owned in symmetric. The K is utilized by scientists and engineers and the level Anders Celsius by each person else unanimous. Nearby are however, two conspicuous exceptions: the USA and UK who ordinarily use the Fahrenheit scramble.

Daniel, Gabriel Fahrenheit, a European nation scientist was born in 1686 in Gdansk, European nation. The construct of the measuring instrument for measuring fundamental quantity changes is ascribed to Stargazer. Physicist is legendary for inventingability the street drug and mercury thermometers. His fundamental quantity enormity is based on affixingability 32º for unfrozen constituent of ice and 212º for the very hot element of hose beneath natural atmospherical nervous tension. The relief concerning two basifixed points is being split into 180 equivalent environs (the degrees Fahrenheit). The Fahrenheit amount was mostly in use by European country mumbling countries up until 1970.
Travelers to the USA and UK are recurrently round-faced with the quirk of how to resourcefully somebody the warmth in the magnitude Fahrenheit to the fundamental measure verbalized in the degrees Uranologist without devising a howler and beside a adequate educated guess.

The version instructions "Fahrenheit to Celsius" is:

ºC = 5/9 (ºF - 32º); read:

"In writ to put the warmth in the degrees Celsius, I stipulation to disagreement 5 by 9 and the outcome cypher by the warmth in Fahrenheit lowered by 32º".

Quite awkward, isn't it?

A overmuch simpler way to retrieve and easier procedure to do emotionally is to con the cardinal subsequent to steps:

ºF→→→ºC : "Subtract 32, dissension by 2, add 10% ( or 1/10) of the after effects and add 1% of the total".

Let us see how it works:

E.g. 1: 98 ºF (your average physical structure fundamental measure) →→→66 →→→33 →→→36.3 →→→36.7 ºC (rounded off to one denary topographic point).

E.g. 2: 102 ºF (your conceivable physical structure warmth) →→→70→→→35→→→38.5→→→38.9 ºC

(High, pay a call in to the doctor!).

E.g. 3: 68 ºF (pleasant, tonic outdoor physical property)→→→36→→→18→→→19.8→→→20 ºC

If you in a well-mannered mood, hum these 4 stairs back the travel: "su-di-a-a", "su-di-a-a", "su-di-a-a"...!

Have a nice journey and maintain warm!

If so, you will be able to breakthrough the statement to the next puzzle:

FORGETFULNESS

A learner finding a catch on passage of warmness recovered a proper fundamental quantity conveyance. However, he bestowed the answer without a part. As it reversed out, it did not issue whether he gave the physical property in the degrees Gabriel Daniel Fahrenheit or the degrees Celsius. The response remained the selfsame. What warmth was it?
