Frequently Asked Questions
-
What does gram/calorie (th) measure?
-
It measures the amount of fuel mass required per thermochemical calorie of energy produced or used.
-
Why convert gram/calorie (th) to kilojoule/kilogram?
-
This conversion helps express fuel efficiency in standard SI energy-per-mass units common in engineering and thermodynamics.
-
Can this tool be used for all calorie definitions?
-
No, it specifically uses the thermochemical calorie (cal_th) definition, which differs from other calorie types.
