What is the formula to convert kelvins to degrees Celsius?

°C = (K × 1 + 0 − 273.15) ÷ 1. For example, 100 K = -173.15 °C.

Is converting kelvins to degrees Celsius just multiplication?

No — kelvins and degrees Celsius have different zero points, so you apply a formula rather than a single factor. For example, 100 K = -173.15 °C.

What is 100 K in °C?

100 K = -173.15 °C. Plugging any K value into the formula °C = (K × 1 + 0 − 273.15) ÷ 1 gives the result in °C.

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.
