Named after Anders Celsius (1710-1744), a Swedish astronomer. A temperature scale in which 0° represents the freezing point and 100° the boiling point of water under standard conditions.
To change Celsius to Kelvin: just add 273.
0 C +273 = 273 K.
To change Celsius to Fahrenheit:
1)
Take the Celsius temperature and multiply by nine-fifths or (9/5) or 1.8.
20 C x 1.8 = 36
2) Then add 32 to get the degrees in Fahrenheit.
36 + 32 = 68
