On this page· Heat per cord
Quick answer
- About 20.4 million BTU per cord at 20% moisture (21.6 GJ).
- A seasoned cord weighs about 3,320 lb (1,510 kg).
- Season it for at least 8 months.
- Ash: moderate. Coals: high. Burn time: long.
Heat per cord
Black cherry is a hardwood. At 20% moisture, a full cord holds about 20.4 million BTU of heat (21.6 gigajoules). Wetter wood gives less, because part of the heat goes into boiling off the water.
That ranks black cherry 412th of the 558 species in our tables, from the hottest down.
Weight and density
A full cord of seasoned black cherry (20% moisture) weighs about 3,320 lb (1,510 kg). Freshly cut, the same cord weighs about 3,990 lb (1,810 kg): the difference is water you don't want to burn.
Its specific gravity, a measure of density, is 0.56. Denser wood packs more heat into each cord.
Seasoning time
Split and stacked off the ground, black cherry needs at least 8 months to dry to about 20% moisture.
Wood dries faster once it is split and stacked with air around it. A moisture meter on a fresh split face tells you when it is ready.
How it burns
- Ash: moderate
- Coals: high
- Burn time: long
We rate black cherry 3 out of 10 as firewood: it burns, but denser species give more heat for the same work.
