Since its definition, the Celsius scale has been redefined to peg it to Kelvin. Zero degrees Celsius is now defined as As one degree Celsius is equal to one Kelvin, boiling point of water is equal to The Fahrenheit temperature range is based on setting the freezing point of water at 32 degrees, and boiling to degrees. This means that boiling and freezing point are degrees apart.

Absolute zero is defined as Boiling and freezing point are therefore degrees apart. Normal body temperature is considered to be Absolute zero is defined as The Celsius scale is nowadays set in such a way that Zero degrees C is the temperature at which ice melts note : not the temperature at which it freezes, which is different!

At the other end of the scale, degrees Celsius is the boiling point of water. The scientific definition of Celsius is now defined against degrees Kelvin. Zero degrees Celsius is One degree Celsius is equal to one Kelvin, so we can say that the boiling point of water is equal to Most things we measure — length, width, time etc. The kelvin and thus Celsius is defined based on the Boltzmann constant, k, which equals 1.

Celsius as a unit and a scale was not widely used until this original definition was inverted. In , the unit, "degree Celsius," as well as the Celsius scale were again re-defined to instead be based on absolute zero This is the definition that was used up until , when the kelvin was redefined based on the definitions of the second, meter, and kilogram. Current use: The Celsius scale replaced the Fahrenheit scale in most countries in the mid to late 20 th century.
