A stands for Anders Celsius – all about plus minus zero since 1742
Anders Celsius, (1701-1744) was a talented Swedish astronomer. He founded Sweden’s first astronomical observatory in Uppsala in 1741. Anders Celsius is best known for the Celsius temperature scale used in thermometers worldwide, °C
Anders Celsius best known for the 100 -degree Celsius temperature scale , which is used worldwide (except in the U.S. , which uses Fahrenheit scale). During the 1700s they used thermometers are widely used, but there was no recognized gradations. It was mostly the outdoor temperature that was measured and was used , among other things, the temperature of a healthy person, the temperature in a deep basement and freezing point of water as a reference.
In total there were over 30 different temperature scales in the early 1700s.
Anders Celsius took the freezing and boiling point at a given pressure as a reference. He made many measurements at different heights, as the water boils at different temperatures depending on the air pressure. Then he put 0 degrees as the boiling point and 100 degrees as the freezing point. He presented his scale in 1742.
After Anders Celsius death turned the scale and the Celsius thermometer was created, with 0 degrees as the freezing point. According to some was Carl Linnaeus one of the first to use the Celsius thermometer and suggested to turn on the scale.
Anders Celsius was a pioneer in Sweden for international cooperation in science and had a rich network of contacts abroad. He had also, according to contemporary witnesses, a winning personality that made him friends where he came.
Abroad were remembered him long in the cities he visited during his long journey, and as late as the 1770s, met other Swedish travelers on many there who remembered him with joy and admiration. He was described as “always happy and cheerful.” Although he was overwhelmed with work, he seemed to never be in a hurry but still made their tasks quickly. He had, according to contemporaries also an abundance of humor, which sometimes could pull the sarcasm.
Celsius died young, at the age of 43 due to tuberculosis.

it’s always room temperature.”
