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

Going the other way is where buyers lose money. A face cord is 42.7 ft³ — you need 3 of them before you have the 128 ft³ a cord requires. Because the depth is whatever the saw decided, a face cord is the one unit here whose volume you cannot know from the name alone.

You are almost certainly here holding a face cord quote and trying to work out whether it is fair. The conversion is the easy part — the useful step is turning both numbers into a price per cord, because that is the only figure a second seller can be honestly compared against.

Worked example

Three face cords at $110 each is $330 for 128 ft³ — 1 cord, so $330 per cord. Quoted against a $300 cord, the face cord deal is the worse one.

Frequently asked questions

How many face cords are in a cord?

+

There are 3 face cords in a full cord, at the standard 16 in cut. A face cord is 42.7 ft³ — one third of a cord's fixed 128 ft³ — so three of them make up one full cord exactly.

What is a face cord of wood?

+

A face cord of wood is a stack 4 ft high and 8 ft long, with a depth equal to whatever length the logs were cut to — commonly 16 in. Unlike the full cord, "face cord" has no legal definition, so the actual volume depends entirely on that cut length.

My invoice says "1 face cord." Is that enforceable?

+

In most states, no. Weights-and-measures law is written around the cord; a receipt naming only a face cord gives an inspector no defined quantity to test against. Ask for the cord-equivalent, or the cut length, written on the receipt.

A seller says his face cords are "big." What does that mean?

+

It means a deeper cut, usually 18 to 20 in rather than 16. That is a genuine 12 to 25 percent more wood, so the claim can be honest — but only if the number is stated. "Big" on its own is not a measurement.

Why convert to cords at all?

+

Because that is the unit a price comparison — and a dispute — has to be settled in. 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.
