What is -253.15 Celsius in Kelvin?

-253.15 °C = 20 K

What is the formula to convert Celsius to Kelvin?

K = °C + 273.15: add 273.15 to the temperature in degrees Celsius. A change of 1 °C is the same as a change of 1 K.

What is absolute zero in Celsius and Fahrenheit?

0 K = -273.15 °C = -459.67 °F: the lowest possible temperature. Kelvins count from it, so a temperature in kelvins is never negative.

Why is the kelvin written without a degree sign?

Since 1967 the kelvin has been an SI unit in its own right, not a degree: a temperature in kelvins is written with the symbol K alone and read as “kelvins”; only °C and °F keep the degree sign.
