# Which symbol(s) represent si units for temperature?

Asked by: Philip Johnson  |  Last update: 18 June 2021

"The kelvin, symbol K, is the SI unit of thermodynamic temperature.

Also, Which is the SI unit for temperature?

The kelvin is the SI unit of thermodynamic temperature, and one of the seven SI base units. Unusually in the SI, we also define another unit of temperature, called the degree Celsius (°C). Temperature in degrees Celsius is obtained by subtracting 273.15 from the numerical value of the temperature expressed in kelvin.

Besides, Is degree Celsius an SI unit?. The "degree Celsius" has been the only SI unit whose full unit name contains an uppercase letter since 1967, when the SI base unit for temperature became the kelvin, replacing the capitalized term degrees Kelvin. The plural form is "degrees Celsius".

Also, What is a symbol that represents Si?

They are the second, with the symbol s, which is the SI unit of the physical quantity of time; the metre, symbol m, the SI unit of length; kilogram (kg, the unit of mass); ampere (A, electric current); kelvin (K, thermodynamic temperature); mole (mol, amount of substance); and candela (cd, luminous intensity).

Which is a symbol that represents SI units for temperature C?

Temperature is a physical quantity that represents the coldness or hotness of a particular system.
