Anders Celsius

Anders Celsius, a Swedish astronomer, was born on 12 November 1701

What is Anders Celsius famous for?

Celsius is famous for his centigrade temperature scale, first described in 1742. He started with the freezing point of water and said it was 0 degrees Celsius (C for short). At the point where water boils, he marked that at 100 degrees C.

Interesting fact: It wasn't until 1948 that the centigrade scale was renamed Celsius temperature scale. Centigrade means "divided into 100 degrees."

The word thermometer is made up of two smaller words:

"Thermo" means heat and "meter" means to measure.

What other measures of temperature are there?

Temperature is measured by a thermometer and can be measured using the scales Fahrenheit, Celsius and another scale called Kelvin. Fahrenheit is used mostly in the United States, and most of the rest of the world uses Celsius. Kelvin is used by scientists.

Who 'invented' the Celsius scale?

Gabriel Fahrenheit devised the Fahrenheit scale of temperature recording in 1724. The freezing point of water on this scale is 32 degrees and the boiling point of water is 212 degrees.

Who 'invented' the Kelvin scale?

The Kelvin scale is named after Lord Kelvin, whose full name is Sir William Thomson, Baron Kelvin of Largs, Lord Kelvin of Scotland. His scale starts at 0 degrees Kelvin, which is called absolute temperature. Water freezes at 273.16K and boils at 373.16K.
