Which quote is actually cheaper?

Two sellers, two units, two species. Price per cord is not enough — oak carries nearly twice the heat of white pine. This compares dollars per MMBtu (one million British Thermal Units — a fixed unit of heat, not a brand or a volume).

How this conversion works

A cord is a fixed 128 ft³. Dividing it into stove cords means slicing that 4 ft × 4 ft × 8 ft block into 3 slabs, each 16 in deep. It is the one term on this list that describes an intended use rather than a fixed shape, which is exactly why it carries no legal weight.

Buying a full cord and asking for it cut to stove length is usually the cheaper route, since you are paying for the enforceable quantity and treating the cut as a service. Work out how many stove cords that yields before you agree a stacking space — a cord at 16 in fills three 4 ft × 8 ft faces.

Worked example

A cord and a half arrives: 4.5 stove cords at a 16 in cut. If the seller stacked to 20 in instead, the same wood is only 3.6 stove cords — fewer units, identical firewood.

Frequently asked questions

How much wall space does a cord need at stove length?

+

Three stacks 4 ft high and 8 ft long, each 16 in deep — 24 linear feet of wall if you stack in one row, or 8 ft of wall three rows deep. Leave a few inches behind the stack for airflow.

Is it cheaper to buy a cord and cut it down myself?

+

Usually, if the wood arrives in longer rounds and you have a saw. The saving is the seller's cutting time, typically $25 to $75 per cord. Buying pre-cut to stove length is worth it if you are storing indoors or lack the space to work.

How many stove cords are in a cord?

+

One cord equals 3 stove cords at the standard 16 in cut. A cord is a fixed 128 cubic feet; a stove cord is 42.7 ft³ of that.

Is a stove cord always exactly a third of a cord?

+

Only at a 16 in cut. At 12 in it is a quarter, at 24 in a half. It is the one term on this list that describes an intended use rather than a fixed shape, which is exactly why it carries no legal weight.

Which unit should the price be quoted in?

+

The cord. The cord is the only firewood measure most states will enforce. NIST Handbook 130, which nearly every state weights-and-measures office adopts, fixes it at 128 cubic feet of ranked and well-stowed wood. Ask for the quantity in cords on the receipt. That is the wording a state inspector can act on.
