The absolute temperature (Kelvin scale) T is related to the temperatur

1.	The absolute temperature (Kelvin scale) T is related to the temperature te on the Celcius scale by tc = T – 273.15 Why do we have 273.15 in this relation and not 273.16?
Answer» We have 273.15 in the relation and not 273.16 because the triple point of water is 0.01 °C and not 0°C. In other words, 0.01 °C → 273.16 K ⇒ 0°C → 273.15 K ∴ t_c = T – 273.15.

Answer»

We have 273.15 in the relation and not 273.16 because the triple point of water is 0.01 °C and not 0°C. In other words, 0.01 °C → 273.16 K

⇒ 0°C → 273.15 K

∴ t_c = T – 273.15.
