❓ FAQ
K to °C FAQ.
What is 300 K in Celsius?
300 K equals 26.85 °C. Using the formula °C = K − 273.15, you convert directly without a lookup table. The reference table on this page lists more common Kelvin values converted to Celsius.
How do you convert Kelvin to Celsius?
Apply the formula °C = K − 273.15. Temperature scales don't share a zero point, so you can't just multiply by a single factor the way you would for length or weight. You have to shift as well as scale. For example, 300 K works out to 26.85 °C.
Why isn't Kelvin to Celsius a simple multiplication?
Because the two scales start at different points. Kelvin is used for the SI temperature unit, used in science, while Celsius is used for everyday temperature in most of the world. Converting between them means both rescaling the degree size and offsetting the zero, which is why the formula has both a multiply and an add or subtract.
