Interview Question - What are the different types of temperature units?



Different Temperature Scales Are-

Celsius -

Celsius scale is developed by a Swedish astronomer Anders Celsius.

By international agreement the unit degree Celsius and the Celsius scale are currently defined by two different temperatures: absolute zero and the triple point of VSMOW (Vienna Standard Mean Ocean Water)

triple point of water is defined as 273.16K or 0.01deg C,the point at which water exists as vapor,solid and liquid.

A degree Celsius (or A kelvin) is what you get when divide the thermodynamic range between absolute zero and the triple point of water into 273.16 equal parts.

In 1948,it was renamed Celsius because centigrade had other meanings in Spanish and French.


One of the seven base units in the SI system of units named after the Belfast-Born Glasgow University engineer and physicist William Thomson 1st Baron kelvin.

Based on absolute zero which is 0K or -273.15 deg C or -459.67 deg F. Theoretical point at which all thermal motion stops.


Temperature scale based on one proposed in 1724 by the physicist Daniel Gabriel Fahrenheit freezing of water into ice is defined at 32 degrees,while the boiling point of water is defined to be 212 degrees -on Fahrenheit’s original scale the freezing point of brine was zero degree.
