-
Variations in fuel composition and measurement conditions may affect results
-
Reciprocal nature of liter/joule requires consistent and precise energy units
Frequently Asked Questions
-
What does Btu (th)/cubic foot measure?
-
It measures the thermal energy content per unit volume of a fuel, specifically the number of British thermal units contained in one cubic foot of fuel.
-
What is liter/joule [L/J] used for?
-
Liter per joule indicates the volume of fuel needed to provide one joule of energy, useful for converting energy requirements into fuel volumes.
-
Where is this conversion typically applied?
-
It is used in natural gas utilities for billing, combustion system design, pipeline operations, and estimating fuel consumption in engines and power plants.
Key Terminology
-
Btu (th)/cubic foot
-
A unit measuring the thermal energy content in one cubic foot of fuel, expressing energy density for gaseous fuels.
-
liter/joule [L/J]
-
A unit representing the volume of fuel (in liters) required to supply one joule of energy, used for converting energy needs into fuel volume.
