Question

Which is shows the formula for converting from kelvin to degrees Celsius

Answer 1

C = K - 273.15

Explanation:

A kelvin is the same size as a Celsius degree.

Absolute zero is 0 K and the freezing point of water is 273.15 K.

To get the freezing point of water to be 0 °C, we must subtract 273.15 from the Kelvin reading (see Figure).

C = K – 273.15

C = 273.15 – 273.15

C = 0 °C

To get absolute zero on the Celsius scale, we repeat the process.

C = 0 – 273.15

C = –273.15 °C
