Scales that aren't calibrated are unreliable.
The Kelvin scale is calibrated at absolute zero, which is the coldest temperature possible where particles stop moving and have zero thermal energy. This temperature is equivalent to -273.15 degrees Celsius.
The Celsius scale is calibrated so that zero Celsius is the freezing point of water at sea level, and one hundred degrees Celsius is the boiling point of water at sea level.
If you mean the temperature of boiling water then Celsius or Centigrade scale
Celsius is measured using a thermometer that is calibrated in degrees Celsius. The scale is typically based on the freezing and boiling points of water, which are 0°C and 100°C, respectively. Temperatures are recorded in Celsius with the symbol "°C".
The Celsius scale is also known as the Centigrade scale.
Centigrade degrees or the "Celsius" scale.
The Celsius scale, of course. Though it is also known as the centigrade scale.
Anders Celsius, a Swedish astronomer, created his temperature scale in 1742.
50 degrees is hotter on the Celsius scale, as 50 degrees Celsius is equivalent to 122 degrees Fahrenheit.
Water boils at 100 degrees Celsius on the Celsius temperature scale.
Andres Celsius developed a similar temperature scale that was the reverse of modern scale. The Celsius scale was named after the Swedish astronomer Anders Celsius(1701-1744). Swedish biologist, Linnaeus developed our modern Celsius scale and named it after Anders Celsius.
The lowest temperature (absolute zero) on the Celsius scale is -273.15°
