Cord Of Firewood Calculator

The cord of firewood calculator is a valuable tool for individuals looking to purchase firewood, as it helps estimate the amount of wood they need to buy. But before diving into the calculator, it’s essential to understand what a cord of firewood is and how it’s measured.

A cord of firewood is a unit of measure that represents a stack of wood that is 4 feet high, 4 feet wide, and 8 feet long. This measurement is equivalent to 128 cubic feet of wood. However, it’s crucial to note that the actual amount of usable wood in a cord can vary depending on the size and shape of the logs, as well as how they are stacked.

To calculate the volume of a cord of firewood, you can use the following formula:

Volume = Length x Width x Height

In the case of a standard cord, the calculation would be:

Volume = 8 feet x 4 feet x 4 feet = 128 cubic feet

However, if you’re looking to calculate the amount of firewood you need to purchase, you’ll want to consider factors such as the size of your fireplace or woodstove, the type of wood you’re burning, and the frequency of use.

Here’s a sample cord of firewood calculator that you can use to estimate your needs:

Firewood Calculator

1. What is the size of your fireplace or woodstove?

   • Small (less than 30,000 BTU)
   • Medium (30,000-50,000 BTU)
   • Large (50,000-70,000 BTU)
   • Extra Large (more than 70,000 BTU)

2. What type of wood are you burning?

   • Softwood (e.g., pine, spruce)
   • Hardwood (e.g., oak, maple)
   • Mixed

3. How often do you plan to use your fireplace or woodstove?

   • Occasionally (less than 1 hour per day)
   • Frequently (1-3 hours per day)
   • Daily (more than 3 hours per day)

4. What is your desired burn time per cord?

   • 1-2 weeks
   • 2-4 weeks
   • 4-6 weeks
   • More than 6 weeks

Based on your inputs, the calculator can estimate the number of cords you’ll need to purchase to meet your firewood needs.

Calculation Example

Let’s say you have a medium-sized fireplace (40,000 BTU) and you plan to burn hardwood (oak) on a frequent basis (2 hours per day). You want your firewood to last for 4-6 weeks. Based on these inputs, the calculator might estimate that you’ll need 2-3 cords of firewood to meet your needs.
