Result
How it works
- Pick two wood species to compare.
- See their estimated BTU output per cord.
- See the relative heat difference between them.
The method
Standard BTU-per-cord reference values for common wood species are compared directly, assuming properly seasoned, dry wood.
FAQ
What does BTU per cord measure?
It measures the total heat energy a full cord of a given wood species produces when burned, letting you compare how much heat you get per load regardless of species.
Why do hardwoods burn hotter than softwoods?
Hardwoods like oak and hickory are denser, packing more burnable material into the same volume, so a cord produces more total heat than a less dense softwood like pine.
Does moisture content affect BTU output?
Yes significantly — wet or unseasoned wood wastes energy evaporating moisture instead of producing heat, so these figures assume properly seasoned, dry wood.
