Frequently Asked Questions
-
What does gram/calorie (IT) measure?
-
Gram/calorie (IT) measures how many grams of a substance are required to deliver one International-Table calorie of energy, indicating mass per unit of thermal energy.
-
Why would I convert g/cal to kg/kJ?
-
Converting g/cal to kg/kJ allows translating mass-per-energy measurements between calories and kilojoules and scaling from grams to kilograms for consistent fuel mass estimation.
-
Are combustion efficiency and fuel type considered in this conversion?
-
No, the unit conversion calculates mass per energy based on unit definitions only and does not account for combustion efficiency or fuel-specific characteristics.
Key Terminology
-
Gram/calorie (IT) [g/cal]
-
A unit measuring mass per International-Table calorie of energy, indicating how many grams are needed to produce one calorie (IT) of energy.
-
Kilogram/kilojoule [kg/kJ]
-
A unit representing mass required per kilojoule of energy, used to quantify fuel or mass consumption per energy output.
-
International-Table calorie (cal IT)
-
A calorie unit defined as 4.1868 joules, used as the basis for gram/calorie (IT) measurements.
