If you convert Celsius to Fahrenheit, you just have to multiply the temperature in °C to 1.8 and add 32.
So if you convert 20°C to °F, it would equal to "68°F"
F = (20 x 1.8) + 32
F = 36 + 32
F = 68°F
If you want it to convert to Kelvin, then this is the formula:
K = Celsius + 273.15
K = 20 + 273. 15
K = 293.15 K
20°C in Kelvin is "293.15 K"
Hope this helps. :D
