What is the formula for Celsius to kelvin?

K = °C + 273.15. 25 °C is 298.15 K.

What is 0 °C in kelvin?

273.15 K — the freezing point of water. At sea-level pressure water boils at about 100 °C, or about 373.15 K.

What is absolute zero?

0 K, which is −273.15 °C and −459.67 °F — nothing can be colder.

Why is there no degree sign on kelvin?

The kelvin is an SI base unit written as K, without a degree sign: 300 K, not 300 °K.

Is a change of 1 °C the same as 1 K?

Yes — the two scales have the same size of degree and differ only in where zero is.
