A full cord of wood is a standard unit of measurement for firewood, commonly used in the United States. Knowing how much a full cord of wood weighs is essential for purchasing, transportation, and heating calculations. In this article, we’ll provide you with accurate and concise information about the weight of a full cord of wood.
Defining a Full Cord of Wood
Before delving into the weight, it’s crucial to understand what constitutes a full cord of wood. A full cord is a neatly stacked volume of wood that measures 4 feet in height, 4 feet in width, and 8 feet in length. This volume equals 128 cubic feet of wood. It’s the standard unit for measuring firewood in the United States.
Wood Types and Variations
The weight of a full cord of wood can vary significantly depending on the type of wood being used. Different wood species have varying densities and moisture content, which directly impacts the weight. Here are some common wood species and their approximate weights when fully seasoned (dried):
Oak: On average, a full cord of oak wood weighs between 4,700 and 6,100 pounds. Oak is a dense hardwood and one of the heaviest woods used for burning.
Hickory: Hickory is another dense hardwood, with a full cord typically weighing between 4,700 and 6,100 pounds, similar to oak.
Maple: A full cord of maple wood, which is also a hardwood, generally weighs between 4,500 and 5,800 pounds.
Pine: Softwood species like pine are less dense. A full cord of pine wood usually weighs between 2,800 and 3,700 pounds.
Moisture Content Matters
The moisture content of the wood significantly affects its weight. Green or freshly cut wood contains a high moisture content, making it heavier than well-seasoned or "dry" wood. As wood dries, it loses moisture, becoming lighter.
To estimate the weight of a full cord of wood accurately, it’s essential to consider the wood’s moisture content. Firewood is typically sold and measured when it is dry, with a moisture content of around 20% or less. This ensures that you’re paying for the energy content of the wood rather than excess water weight.
Conclusion
The weight of a full cord of wood varies depending on the type of wood and its moisture content. Understanding these factors is crucial when purchasing firewood, as it can impact transportation, storage, and heating efficiency. Dry, well-seasoned wood is lighter and more efficient for burning, so be sure to confirm the moisture content of your firewood when buying it to get the best value and performance from your wood-burning stove.
