The point where all three phases are shown of water is known as triple point of water.
Triple point of water T = 273.16°K
Let t represent the Celsius temperature then
t = T – 273.15°C
Where t is Celsius temperature °C and Kelvin temperature T(°K)
T°F = 9/5T°C + 32 = 9/5 × 0.01 + 32 = 32.018°F
T°R = 9/5T°K = 9/5 × 273.16 = 491.7 R
T°C = 9/5(T°K–32)
TK = t°C + 273.16
TR = t°F + 459.67
TR/TK = 9/5
