Kelvin is a unit of temperature.
The freezing/melting point of water is about 273.15K at a pressure of 1 atmosphere.
The symbol of Kelvin unit is K.
Celsius or centigrade is a unit of temperature.
The freezing/melting point of water is about zero degrees celsius (0 °C) at a pressure of 1 atmosphere.
The boiling point of water is about one hundred degrees celsius (100 °C) at a pressure of 1 atmosphere.
The exact values depend on the water composition (usually the amount of salt) and the air pressure.
Seawater contains salt and the freezing point is reduced below 0 °C.
When boiling water on a mountain above sea level the boiling point is reduced below 100 °C.
The symbol of Celsius degrees is °C.
0 Kelvin is equal to -273.15 degrees Celsius:
0 K = -273.15 °C
The temperature T in degrees Celsius (°C) is equal to the temperature T in Kelvin (K) minus 273.15:
T(°C) = T(K) - 273.15
Convert 300 Kelvin to degrees Celsius:
T(°C) = 300K - 273.15 = 26.85 °C
