Frequently Asked Questions
-
What does calorie (th)/gram measure?
-
It measures specific energy, indicating how many thermochemical calories of energy are contained per gram of material.
-
Why use kilogram/kilojoule units?
-
Kilogram per kilojoule expresses the mass required per unit of energy, useful for converting energy requirements into fuel mass estimates in engineering.
-
How is the conversion factor applied?
-
Multiply the value in calorie (th)/gram by 0.2390057361 to obtain the equivalent value in kilogram/kilojoule.
Key Terminology
-
Calorie (th)/gram [cal (th)/g]
-
A unit measuring the thermochemical calorie energy contained per gram of material; 1 cal (th)/g equals 4.184 joules per gram.
-
Kilogram/kilojoule [kg/kJ]
-
A unit expressing mass per unit of energy, representing how many kilograms of fuel or material are needed to provide one kilojoule of energy.
-
Specific Energy
-
The amount of energy per unit mass of a material, such as calories per gram or joules per kilogram.
