What is the formula to convert degrees Celsius to kelvins?

K = (°C × 1 + 273.15 − 0) ÷ 1. For example, 100 °C = 373.15 K.

Is converting degrees Celsius to kelvins just multiplication?

No — degrees Celsius and kelvins have different zero points, so you apply a formula rather than a single factor. For example, 100 °C = 373.15 K.

What is 100 °C in K?

100 °C = 373.15 K. Plugging any °C value into the formula K = (°C × 1 + 273.15 − 0) ÷ 1 gives the result in K.

Temperature

Celsius, Fahrenheit, Kelvin — three zeros, three worlds

Fahrenheit's zero was a slurry of ice, water and sal ammoniac, reproducible in an Amsterdam workshop. Celsius's zero meant boiling water for three years. Kelvin's zero is a limit the universe never crosses. Three scales, and three entirely different answers to the question of where counting heat should begin.
