What Is This Tool?
This converter transforms fuel efficiency measurements from pound per Btu (IT) to calorie (IT) per gram, enabling users to evaluate fuel mass consumed per unit heat energy and express it as specific energy. It supports applications in combustion, thermal power, and fuel specification.
How to Use This Tool?
-
Enter the value in pound per Btu (IT) you wish to convert.
-
Select pound/Btu (IT) as the input unit and calorie (IT)/gram as the output unit.
-
Initiate the conversion to obtain the corresponding specific energy in cal/g.
-
Use the results to compare fuel energy densities or for design calculations.
Key Features
-
Simple conversion between lb/Btu (IT) and cal (IT)/g based on International Table standards.
-
Useful for combustion engineering and thermal power calculations.
-
Browser-based with no installation required.
-
Supports fuel selection and emissions assessment analytics.
Examples
-
Convert 2 lb/Btu (IT) to calories/gram: 2 × 0.5555555556 = 1.1111111112 cal/g.
-
Convert 0.5 lb/Btu (IT) to calories/gram: 0.5 × 0.5555555556 = 0.2777777778 cal/g.
Common Use Cases

Tips & Best Practices
-
Ensure consistent use of International Table standards for units when converting.
-
Use conversion results to support theoretical evaluations of fuel performance.
-
Consider fuel composition variability when applying converted values.
-
Apply converted data within relevant engineering or fuel specification contexts.
Limitations
-
Conversion is based strictly on International Table definitions for Btu and calorie.
-
Fuel composition and operational conditions can affect actual heating values.
-
The calculated equivalences are theoretical and may not match exact practical values.
-
Overly precise decimal values may not reflect real measurement accuracy.
Frequently Asked Questions
-
What does pound per Btu (IT) measure?
-
It measures the amount of fuel mass consumed per unit of heat energy produced, using the International Table British thermal unit.
-
Why convert lb/Btu (IT) to calorie (IT)/gram?
-
Converting allows expressing fuel efficiency as specific energy, helping compare fuels and support combustion and engine calculations.
-
Is this conversion exact for all fuels?
-
No, actual heating values can vary with fuel composition and conditions; this conversion provides theoretical equivalences.
