centigrade

Joule

Celsius

Kelvin

The SI unit used in measuring the temperature of a hot cup of coffee is Kelvin.

Explanation:

The metric system (International System of Units) is the most common system that is recognized internationally for the measurements of mass, length, temperature, time, electric current, luminous intensity, etc. Kelvin (K) is the International System of Units (SI) for measuring the temperature. The formula for converting a temperature in Celsius to Kelvin scale is; Kelvin = Celsius + 273.15. The Celsius and Fahrenheit scales are mostly used in daily purposes like food preparation, weather forecasts, etc. Kelvin is usually used by scientists in equations for temperatures in physics and chemistry.
