What Is This Tool?
This converter transforms values from pound per horsepower-hour, a fuel mass consumption measure used in engine efficiency testing, to calorie (IT) per gram, which expresses the energy content per mass of a substance. It aids in linking engine fuel consumption rates to fuel energy density for better performance assessment.

Key Terminology
-
Pound/horsepower/hour
-
A unit that expresses the mass of fuel consumed per horsepower of output over one hour, used to assess engine fuel efficiency.
-
Calorie (IT)/gram
-
A specific-energy unit measuring the amount of energy contained per gram of a substance, based on the International Steam Table calorie.
-
Brake Specific Fuel Consumption (BSFC)
-
A measure of fuel efficiency in engines, expressed as the amount of fuel used to produce a unit of power over time.
