Swedish astronomer Anders Celsius developed his original centigrade temperature scale on December 25, 1741. He presented his findings to the Royal Society of Sciences in Uppsala, Sweden in 1742.
It is worth noting that Celsius's original scale was the reverse of the
one used today:
- He set
the boiling point of water at 0 degrees.
- He set
the freezing point of water at 100 degrees.
The scale was reversed to its modern form (0° for freezing, 100° for
boiling) shortly after his death, most notably by fellow Swedish scientist Carl
Linnaeus in 1745, to make it more practical for everyday use. The scale was
officially renamed the "Celsius scale" in his honor in 1948 by an
international conference.
