Here's why:
* Celsius' work: Celsius, a Swedish astronomer, proposed his temperature scale in 1742, based on the freezing and boiling points of water.
* Location: Celsius' work was likely conducted in Uppsala, Sweden, where he was a professor at Uppsala University. However, his scale was a scientific concept, not tied to a specific place.
Therefore, it's more accurate to say that Celsius invented the Celsius scale while working in Uppsala, Sweden, rather than at a specific location.
