Celsius (°C) is a temperature scale based on the freezing and boiling points of water, while Kelvin (K) is an absolute temperature scale. Celsius starts at 0° when water freezes, while Kelvin starts at 0K, which is equivalent to -273.15°C. Celsius is used for everyday temperatures, while Kelvin is used in scientific calculations.

Celsius and Kelvin: What's the Difference?

Celsius: A measure of temperature on a relative scale, where 0 degrees is the freezing point of water and 100 degrees is the boiling point of water. Kelvin: A measure of temperature on an absolute scale, where 0 degrees is absolute zero and 273.16K is the freezing point of water. Celsius to Kelvin Conversion: The equation to convert Celsius to Kelvin is C + 273.16 = K, where C is the temperature in Celsius and K is the temperature in Kelvin.

Celsius and Kelvin are both named after the Swedish astronomer, Anders Celsius. Celsius and Kelvin are the same scale, but the numbers are offset by 273.15 degrees. The kelvin is the only SI unit to be named after a person. 0 Kelvin is when all movement of particles stops.
