Yes it is.
degrees celsius
The temperature in Fahrenheit is no SI unit. Use kelvin or degrees Celsius instead.
The SI unit of temperature is Kelvin, but degrees Celsius is a derived SI unit for temperature and more commonly used.
kelvin
The metric unit is degrees Celsius and the SI fundamental unit is the Kelvin.
The basic unit of temperature is the degree Celsius (°C) in the International System of Units (SI).
The SI unit of temperature is kelvin.Everyday temperatures are quoted in degrees Celsius.
The most common units for temperature are Celsius (°C) and Fahrenheit (°F), which are both measured in degrees. Another unit for temperature is Kelvin (K), which is the SI unit and is not measured in degrees.
For the same reason as we don't say 'degrees ampere' or degrees metre'! Remember, kelvin is an SI unit, and follows SI conventions. Celsius in not an SI unit, so follows different conventions.
The scale used is usually Celsius or Kelvin.AnswerThe SI unit of temperature is the kelvin (K). Celsius is a metric unit, but not an SI unit, although it may be 'used alongside' the SI system.
Kelvin is the SI unit for thermodynamic temperature. symbol: K (there are no degrees, unlike °C and °F).
Degrees Celsius. Absolute (SI units) are Kelvin=degC+273.15
