Frequently Asked Questions
-
What does pound per Btu (th) measure?
-
It measures mass-based fuel consumption, indicating how many pounds of fuel are used to produce one British thermal unit of heat.
-
Why convert pound/Btu (th) to kilojoule/kilogram?
-
To translate mass-based fuel usage into an energy per mass unit that helps compare fuel calorific values and optimize fuel efficiency.
-
Can this conversion be applied to all fuels?
-
The conversion applies generally but requires careful calibration due to fuel composition and measurement standard differences.
Key Terminology
-
Pound per Btu (th) [lb/Btu (th)]
-
A unit representing the pounds of fuel required to produce one British thermal unit of thermal energy, used to assess fuel consumption based on mass.
-
Kilojoule per kilogram [kJ/kg]
-
A unit indicating how many kilojoules of energy correspond to each kilogram of a substance, used widely for specific energy and enthalpy measurements.
-
Fuel efficiency
-
A measure of how effectively a fuel converts mass into usable energy within a thermal or combustion system.
