A cord is a unit of volume used to measure firewood, equivalent to 128 cubic feet (3.62 cubic meters). The weight of this volume of hardwood, however, is not fixed. Factors such as tree species, moisture content, and how tightly the wood is stacked significantly influence the total mass. A tightly packed cord of dense hardwood like hickory, for example, will weigh considerably more than a loosely stacked cord of lighter wood like aspen, even if both are equally dry.
Accurately estimating the weight is crucial for both buyers and sellers of firewood. Fair pricing relies on understanding the energy content provided, which is directly related to the wood’s mass. Transportation costs are also affected by the weight, and knowing this beforehand helps prevent overloading vehicles or underestimating delivery expenses. Historically, the cord has been a standard unit for wood measurement, facilitating trade and ensuring a common understanding between parties. Its continued use underscores the enduring need for a consistent volume metric in the firewood industry.
