A cord is a unit of volume measuring stacked firewood, equivalent to 128 cubic feet (3.62 cubic meters). The weight of this volume of wood, however, varies significantly depending on several factors. These factors include wood species, moisture content, and how tightly the wood is stacked. A tightly packed cord will naturally weigh more than a loosely packed one, even with the same wood species and moisture level. For instance, a cord of dense hardwood like hickory can weigh considerably more than a cord of lighter softwood like pine.
Understanding the weight of a given volume of firewood is crucial for both sellers and buyers. Fair pricing depends on accurate measurement, and weight offers a more precise method than simple volume, especially given the variability in stacking practices. Historically, firewood has served as a primary heating fuel, and its consistent measurement ensured fair trade. Today, knowing the expected weight can also aid in planning transportation and storage logistics. The ability to accurately estimate weight prevents overloading vehicles and ensures adequate structural support for storage.
