Question

Hi i was wondering if you could help me understand Kelvins? My question on my work says "Which of the following is the SI unit used in measuring the temperature of a hot cup of coffee" and the other question says, "Which of the following would be the SI unit to use in measuring the temperature of a hot liquid?" I said both are Kelvin but i dont really understand and i dont want to be wrong. ​

Answer 1

Hey there!

Kelvin is correct. Farenheit and Celsius are scales derived from the Kelvin scale. For example, K=C+273.15 is the conversion between Kelvin and Celsius.

Let me know if this helps :)
