Frequently Asked Questions
-
What does gram/calorie (th) measure?
-
Gram/calorie (th) represents the mass of fuel consumed per thermochemical calorie of energy produced, expressing fuel efficiency in mass-to-energy terms.
-
Why convert from gram/calorie (th) to joule/kilogram?
-
Converting to joule/kilogram expresses specific energy in SI units, enabling standardized energy content comparison per mass and reliable thermodynamic calculations.
-
Can I use this conversion for other calorie types?
-
No, this conversion is specific to the thermochemical calorie definition and requires adjustment to be valid for other calorie forms.
