Frequently Asked Questions
-
What does calorie (th)/gram measure?
-
Calorie (th)/gram measures the specific energy, indicating how many thermochemical calories of energy are contained per gram of material.
-
Why convert calorie (th)/gram to joule/kilogram?
-
Converting to joule/kilogram expresses specific energy in the SI unit, allowing easier comparison, calculation, and integration in scientific and engineering contexts.
-
Can this conversion be used for total energy values?
-
No, this conversion applies only to specific energy values normalized per unit mass and not to total energy values without mass normalization.
