What Is This Tool?
This tool converts fuel efficiency mass units from pound per British thermal unit (thermal) [lb/Btu (th)] to grams per kilowatt-hour (g/kW·h). It helps translate mass-based fuel consumption values from thermal energy terms into specific fuel consumption per electrical or mechanical energy output.
How to Use This Tool?
-
Input the value in pound/Btu (th) representing mass of fuel per unit thermal energy
-
Select the output unit as gram/kilowatt/hour for specific fuel consumption
-
Click the convert button to obtain the equivalent value in grams per kWh
-
Use the converted result for design, performance evaluation, or benchmarking tasks
Key Features
-
Converts between mass-per-energy units used in fuel efficiency analyses
-
Supports fuel consumption metrics for boilers, engines, turbines, and generators
-
Browser-based and straightforward to use without complicated inputs
-
Facilitates comparison of fuel efficiencies across different energy systems
Examples
-
0.5 lb/Btu (th) converts to 774378.585086 g/kW·h
-
2 lb/Btu (th) converts to 3097514.340344 g/kW·h
-
Multiply the input value by 1548757.170172 to get the result in g/kW·h
Common Use Cases
-
Specifying fuel consumption for boilers and furnaces in industrial thermal systems
-
Comparing fuels based on mass-per-energy for industrial burner selection
-

Large conversion factor can pose challenges for numerical precision and calculation
-
Users must ensure appropriate context when applying converted values for system comparisons
Frequently Asked Questions
-
What does pound/Btu (th) measure?
-
Pound/Btu (th) measures the mass of fuel in pounds required to produce one British thermal unit of heat energy.
-
Why convert lb/Btu (th) to gram/kilowatt/hour?
-
This conversion enables comparison of mass-based fuel consumption from thermal energy terms to specific fuel consumption per electrical or mechanical energy output for various applications.
-
Is the conversion factor always the same?
-
Yes, the conversion factor from pound/Btu (th) to gram/kilowatt/hour is fixed at 1 lb/Btu (th) = 1,548,757.170172 g/kW·h.
Key Terminology
-
Pound/Btu (th) [lb/Btu (th)]
-
A unit expressing the pounds of fuel required to generate one British thermal unit (thermal) of heat, used to quantify mass-based fuel consumption.
-
Gram/kilowatt/hour (g/kW·h)
-
A unit representing grams of fuel consumed per kilowatt-hour of energy produced, indicating specific fuel consumption.
-
Specific Fuel Consumption
-
A measure of fuel efficiency showing fuel mass required per unit of energy output, commonly in g/kW·h.
