What is a unit of specific heat?

An example of a unit of specific heat is cal / g ?C. Specific heat is usually the unit of heat divided by the product of the quantity of a substance and the substance's temperature change. This can be written as heat / (quantity x temperature change).

In science, heat is generally measured in calories or joules, the quantity of a substance is measured in grams or moles, and the temperature change of a substance is measured in Celsius, Fahrenheit or Kelvin. Depending on the materials being used to measure a substance, these values can be mixed and matched. Examples of other units of specific heat are joules / mole ?K, calories / g ?F and joules / g ?C.
