Frequently Asked Questions
-
What does calorie (IT)/gram measure?
-
It measures the amount of energy, in International Steam Table calories, contained per gram of a substance, representing energy density on a mass basis.
-
Why convert calorie (IT)/gram to kilogram/kilojoule?
-
Converting to kilogram/kilojoule helps translate energy density into the mass required per energy unit, which is useful for fuel mass sizing and energy system design.
-
Where is kilogram/kilojoule unit mainly used?
-
It is used in engineering to convert energy needs into fuel or storage mass requirements in propulsion, power plants, and energy-storage system design.
Key Terminology
-
calorie (IT)/gram [cal/g]
