An
easy conversion to remember is: Fahrenheit to Celsius: Subtract 30
and divide by 2. Celsius to Fahrenheit: multiply by 2 and add 30.
(For exact conversions: Fahrenheit to Celsius : subtract 32 and
divide by 1.8. Celsius to Fahrenheit : Multiply by 1.8 and add 32)
During 1742, Swedish astronomer Anders Celsius
created a temperature scale which was the reverse of the scale now
known as Celsius: 0 represented the boiling point of water, while
100 represented the freezing point of water. His scale was
reversed in 1744. For scientific use, Celsius is the term
usually used, with centigrade in common, but decreasing use.
Fahrenheit is a temperature scale based on one proposed in 1724 by
the German physicist Daniel Gabriel Fahrenheit. The scale is usually
defined by two fixed points: the temperature at which water freezes
into ice, 32 degrees, and the boiling point of water, 212 degrees.
Today, the Fahrenheit scale is used primarily in the United States
and some Caribbean countries. The rest of the world uses the Celsius
scale. It does not matter which scale you use at this time of
year where I live, it is just called HOT! In Antarctica it is
COLD!

German Inventions
Although it has now been replaced by the
Celsius temperature scale in almost all countries except for USA and
Belize, Fahrenheit (in which water's freezing point is 32 degrees
and boiling point is 212) was the world standard until relatively
recently. It was invented by German physicist Daniel Gabriel
Fahrenheit in 1724.
Aspirin, made from willow bark was developed by Felix Hoffmann in August 1897 for pharmaceutical giant Bayer, and although a US company claimed a patent for the drug after World War One, 12,000 of the 50,000 tons of Acetylsalicylic acid (Aspirin) produced each year are still made by Bayer.
After using blotting paper from her children’s school books to remove unwanted coffee grounds, Dresden housewife Melitta Bentz had the idea to patent her invention in 1908. She then founded a company selling over a thousand coffee filters by the next year.
German clock manufacturer Junghans Uhren Gmbh developed a watch that automatically adjusts itself to an atomic clock using radio signals. It was invented in 1990 and will remain accurate to the second for at least a million years.
The first true working car was invented by Germans Karl Benz and Gottlieb Daimler in 1886, 22 years before the Model T Ford went into production in the USA.
The first true accordion was invented by a German, Christian Friedrich Buschmann. In 1822 he attached bellows to a portable keyboard with vibrating reeds and called it a "hand-aeoline".
In 1977 after nine years of development, German inventors Jürgen Dethloff and Helmut Göttrup created the first card with a built in programmable microprocessor, the ancestor of the chip and PIN cards in our wallets today.
