Frequently Asked Questions
-
What does pound/Btu (th) measure?
-
Pound per Btu (th) quantifies the pounds of fuel required to produce one British thermal unit of heat, expressing mass-based fuel consumption.
-
Why convert pound/Btu (th) to gram/calorie (th)?
-
Converting to gram/calorie (th) allows comparison of fuel efficiency in different unit systems to better analyze mass-based fuel consumption per thermal energy.
-
Can this conversion be used for all fuels?
-
While useful for many fuels, accuracy depends on fuel composition and consistent definitions of thermal units and calorific values.
