What Is This Tool?
This converter transforms values from joule per kilogram (J/kg), an SI unit of specific energy, into gram per thermochemical calorie (g/cal (th)), which represents mass per unit thermal energy. It helps users compare and calculate fuel efficiency and energy-related metrics across different unit systems.
How to Use This Tool?
-
Enter the numerical value in joule per kilogram (J/kg) you want to convert
-
Select joule/kilogram as the input unit and gram/calorie (th) as the output unit
