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

Cubic feet are the common denominator underneath every name on this site. A bush cord resolves to 128 ft³ — a 4 ft × 8 ft face at 48 in deep. A bush cord is the full 128 ft³ — the same legally enforceable quantity, under a regional name.

Most bush cord quotes come from Canadian sellers, which makes the cubic-foot figure a useful bridge: 128 ft³ is 3.62 cubic metres. If a supplier quotes in cubic metres, that is the number to convert against, and it is the one place where the two measurement systems have to meet on a firewood invoice.

Worked example

A pickup bed 6 ft long, 4 ft wide and stacked 2 ft high holds 48 ft³ — 0.375 of a bush cord. Two of those loads still fall short of one.

Frequently asked questions

How many cubic metres is a bush cord?

+

About 3.62 m³ of stacked wood, from 128 ft³. Canadian sellers who quote in cubic metres are usually quoting stacked volume too, but confirm it — loose-thrown volume runs roughly a third higher for the same wood.

Do Canadian sellers quote stacked or loose volume?

+

Stacked, by convention and under the Weights and Measures Act. Loose or "thrown" cubic metres run about a third higher for identical wood, so confirm which one a quote refers to before converting it.

How many cubic feet are in a bush cord?

+

128 cubic feet, fixed by statute in most states. A bush cord is the full 128 ft³ — the same legally enforceable quantity, under a regional name.

Why work in cubic feet rather than bush cords?

+

Because cubic feet survive the trip between regions and sellers. The cubic foot is the measure every other name on this site resolves to, and the one that never depends on a region or a saw.

How do I measure the cubic feet of a delivery myself?

+

Restack it square, then multiply height × length × depth in feet. A stack 4 ft high, 8 ft long and 16 in (1.33 ft) deep comes to 42.7 ft³. Do it before the driver leaves.
