-
Users must ensure correct direction of conversion to avoid errors in calculations
Frequently Asked Questions
-
What does calorie (IT)/gram measure?
-
It measures the energy contained per gram of a substance expressed in International Steam Table calories, used mainly for fuel energy density.
-
What is pound/Btu (th) used for?
-
Pound per Btu (th) indicates the mass of fuel needed to produce one British thermal unit of heat, useful for evaluating fuel consumption efficiency.
-
Why convert from calorie (IT)/gram to pound/Btu (th)?
-
This conversion enables switching from an energy per mass representation to a mass per energy perspective, facilitating thermal system fuel efficiency evaluations.
