The Kelvin temperature scale, named after the first Lord Kelvin (Sir William Thomson), is a thermodynamic temperature scale for all universal events, such that all temperatures in this scale are positive. To date, it has not been possible to reach to absolute zero Kelvin, although the approach has come close.
Conversion to the Celsius (or Centigrade scale) is very simple: just add 273.15 ° to any Kelvin temperature.
K = °C + 273.15
K = temperature, Kelvin
°C = temperature, degrees Celsius (Centigrade)
Kelvin to Celsius Formula Questions:
1) Water freezes at 0° C. What is the temperature in Kelvin?
Answer: Temperature, Celsius = 0° C. Use the formula.
K = °C + 273.15
K = 0°C + 273.15
K = 273.15
