What Is This Tool?
This tool converts values between pound/Btu (thermal), which measures mass per unit energy, and Btu (International Table) per pound, representing energy content per unit mass. It helps evaluate fuel efficiency and energy density in various thermal applications.
How to Use This Tool?
-
Enter the value in pound/Btu (th) units that you want to convert.
-
Select pound/Btu (th) as the input unit and Btu (IT)/pound as the output unit.
-
Click convert to obtain the equivalent value in Btu (IT)/pound.
Key Features
-
Converts fuel efficiency units based on mass and energy relationships.
-
Supports analyses for boilers, furnaces, HVAC, and industrial combustion systems.
-
Facilitates comparisons of fuel energy density for selection and performance assessments.
Examples
-
Convert 2 pound/Btu (th) to Btu (IT)/pound: result is approximately 1.998662463 Btu/lb.
-
Convert 0.5 pound/Btu (th) to Btu (IT)/pound: result is approximately 0.49966561575 Btu/lb.
