| Stack | 1 row of 16 in pieces, 16 in deep |
|---|---|
| Full cords (128 cu ft) | 0.33 cords |
| 4 × 8 ft faces ("face cords") | 1; each one is 33% of a full cord at this piece length |
| Heat in the wood | 6.7 million Btu (Not sure / mixed (EIA average cord), 20 million Btu per cord) |
| Heat into the house | about 4.7 million Btu in an EPA-certified stove at 71% efficiency |
A "face cord" or "rick" of 16 in pieces holds only 33% of a full cord. NIST Handbook 130's model regulation, which many states have adopted, says sellers should not use "face cord", "rack", "pile" or "truckload", so ask for the amount in cords or fractions of a cord.
Measure the stack tightly piled, with the pieces parallel and touching. A loosely thrown pile has more air and less wood.
