What Is This Tool?
This converter transforms measurements of volumetric energy content from Btu (IT) per cubic foot—the amount of heat energy in one cubic foot of gas—into liter per joule, which indicates how much fuel volume in liters is required to provide one joule of energy.
How to Use This Tool?
-
Enter the value in Btu (IT) per cubic foot you wish to convert
-
Choose the target unit as liter per joule [L/J]
-
Click convert to see the equivalent volume per energy unit
-
Apply the result to fuel volume or energy consumption calculations
Key Features
-
Converts Btu (IT)/cubic foot to liter/joule with a clear, reliable formula
-
Supports understanding of fuel volume relative to energy content
-
Browser-based and simple to use for engineers and analysts
-
Useful in energy billing, combustion system design, and fuel comparison
Examples
-
10 Btu (IT)/ft³ converts to 0.26839192 L/J by multiplying 10 × 0.026839192
-
50 Btu (IT)/ft³ equals 1.3419596 L/J using 50 × 0.026839192

Frequently Asked Questions
-
What does Btu (IT)/cubic foot measure?
-
It measures the amount of heat energy contained in one cubic foot of gaseous fuel, expressed as International Table British thermal units per cubic foot.
-
Why convert Btu (IT)/cubic foot to liter/joule?
-
Converting to liter/joule helps express the volume of fuel required to produce a unit of energy, assisting in fuel volume calculations and comparisons.
-
Can this conversion be used for billing natural gas?
-
Yes, it is commonly applied to translate volumetric gas deliveries into energy content for utility billing purposes.
Key Terminology
-
Btu (IT)/cubic foot [Btu/ft³]
-
A volumetric energy measure indicating the heat energy in one cubic foot of gaseous fuel based on International Table British thermal units.
