Within the woodworking industry, the phrase “cord of wood” is casually used to describe a large quantity of wood, often used for firewood. However, this term can be misleading as it may not accurately reflect the true volume of wood being purchased. To ensure precision and avoid misunderstandings, it’s essential to delve into the proper measurement techniques for quantifying wood, specifically focusing on the unit of a quart.
The term “quart” is typically employed to measure liquids, but it can also be applied to determine the volume of solid materials, including wood. A quart of wood is equal to one-fourth of a standard cord, which is commonly recognized as the industry standard for firewood measurement. A cord of wood encompasses 128 cubic feet, so a quart would be equivalent to 32 cubic feet. Understanding this conversion factor is crucial for buyers to accurately estimate the amount of wood they require and to make informed purchasing decisions.
Measuring a quart of wood involves a straightforward process. Firstly, gather the wood pieces to be measured and stack them neatly in a rectangular pile. Ensure that the wood is arranged compactly, minimizing any gaps or empty spaces. Next, measure the length, width, and height of the pile using a measuring tape or ruler. Multiply these three measurements together to obtain the volume in cubic feet. Finally, divide the total cubic footage by 32 to determine the quantity of quarts represented by the wood pile. By following these steps, you can accurately measure a quart of wood, ensuring fairness and transparency in your wood-related transactions.
Determining the Volume of Cordwood
Cordwood is a term used to describe firewood that has been cut into uniform pieces, typically 16 inches in length. The volume of cordwood is typically measured in cords, which are equal to 128 cubic feet. To determine the volume of cordwood, you will need to know the length, width, and height of the stack.
Once you have these measurements, you can use the following formula to calculate the volume:
| Volume (cords) = Length (feet) x Width (feet) x Height (feet) / 128 |
|---|
Example: If you have a stack of cordwood that is 8 feet long, 4 feet wide, and 4 feet high, the volume would be:
| Volume (cords) = 8 x 4 x 4 / 128 = 0.5 cords |
|---|
It’s important to note that the formula only gives an approximation of the volume. The actual volume may vary depending on the size and shape of the pieces of wood and how tightly they are packed.
Measuring Units for Wood: The Quart
What is a Quart?
A quart is a traditional unit used to measure volume, commonly used in the measurement of dry commodities like wood in the United States and Canada. It is defined as a quarter of a gallon. In the imperial system, one gallon is equal to 231 cubic inches. Therefore, one quart is equal to 57.75 cubic inches (231 / 4).
Converting Quarts to Other Units
To convert quarts to other volume units, you can use the following conversion factors:
| Unit | Conversion factor |
|---|---|
| Cubic inches | 57.75 |
| Cubic feet | 0.037 |
| Gallons | 0.25 |
| Liters | 0.946 |
Calculating the Length, Width, and Height of the Wood
To accurately measure a quart of wood, it’s essential to determine its dimensions: length, width, and height. Here’s how to calculate each:
Length
Place a measuring tape along the longest side of the wood, ensuring it’s straight and parallel to the edge. Record the measurement in feet or inches.
Width
Measure the perpendicular distance from the edge of the wood to the opposite edge at its widest point. Use a measuring tape or ruler and record the measurement in feet or inches.
Height
To determine the height of stacked wood, follow these steps:
- Stack the wood neatly: Arrange the wood in a pile with pieces aligned and parallel to one another.
- Measure the total height: Position a measuring tape vertically at the base of the wood stack. Extend the tape to the top of the stack and record the height in feet or inches.
- Calculate the average height per piece: Measure the height of 10-15 individual pieces from the stack. Divide the sum of these measurements by the number of pieces to determine the average height per piece.
- Multiply by the number of pieces: To calculate the total height of the wood pile, multiply the average height per piece by the total number of pieces in the stack.
| Measurement | Unit of Measurement |
|---|---|
| Length | Feet or Inches |
| Width | Feet or Inches |
| Height | Feet or Inches |
Converting Linear Measurements to Volume
To convert linear measurements to volume, you’ll need to know the dimensions of the wood and the formula for volume. The formula for the volume of a rectangular prism is:
V = l × w × h
Where:
- V is volume in cubic units
- l is the length in the same cubic units
- w is the width in the same cubic units
- h is the height in the same cubic units
For example, if you have a piece of wood that is 12 inches long, 6 inches wide, and 4 inches high, the volume would be:
V = 12 × 6 × 4 = 288 cubic inches
Once you have the volume in cubic units, you can convert it to quarts using the following conversion factor:
1 quart = 57.75 cubic inches
So, the volume of the piece of wood in quarts would be:
288 cubic inches ÷ 57.75 cubic inches/quart = 5 quarts
Converting Linear Measurements to Volume Using a Table
You can also use a table to convert linear measurements to volume. The following table shows the volume of a rectangular prism in cubic inches for various lengths, widths, and heights.
| Length (inches) | Width (inches) | Height (inches) | Volume (cubic inches) |
|---|---|---|---|
| 12 | 6 | 4 | 288 |
| 18 | 12 | 6 | 1296 |
| 24 | 18 | 8 | 3456 |
To use the table, simply find the row that corresponds to the length, width, and height of your piece of wood. The volume in cubic inches will be listed in the fourth column.
Using the Cordwood Formula
The cordwood formula is another method to determine the quantity of wood in a pile. It works best for neatly stacked wood, such as logs or firewood arranged in a cordwood rack. The formula is as follows:
Formula:
| 1 Cord = | Length x Width x Height |
|---|---|
| (in feet) |
Step 1: Measure the length, width, and height of the stacked wood. Make sure to measure in feet to match the unit of measurement in the cordwood formula.
Step 2: Multiply the length, width, and height measurements. The result will give you the cubic footage of the wood pile.
Step 3: Divide the cubic footage by 128. This converts the cubic footage into cords. One cord is equivalent to 128 cubic feet of stacked wood.
Example:
Let’s say you have a stack of firewood that measures 8 feet long, 4 feet wide, and 4 feet high. Using the cordwood formula:
Cubic footage = Length x Width x Height
Cubic footage = 8 ft x 4 ft x 4 ft
Cubic footage = 128 cubic feet
Number of cords = Cubic footage / 128
Number of cords = 128 cubic feet / 128
Number of cords = 1 cord
Therefore, the stack of firewood contains 1 cord of wood.
Estimating the Volume of Irregular Wood
Measuring the volume of irregular wood can be challenging, but it’s not impossible. Follow these steps to ensure accurate results:
6. Measuring Irregular Pieces
For irregularly shaped wood, measuring the volume becomes more complex. We’ll focus on two methods: the Water Displacement Method and the Formula Method.
Water Displacement Method:
- Submerge the irregular piece in a container filled with water.
- Measure the volume of water displaced by the wood.
- This displaced volume is equal to the volume of the wood.
Formula Method:
- Divide the wood into smaller, regular shapes (e.g., cubes, cylinders, cones).
- Calculate the volume of each regular shape using the appropriate formula.
- Add up the volumes of all the regular shapes to get the total volume of the irregular wood.
| Shape | Formula |
|---|---|
| Cube | V = a3 |
| Cylinder | V = πr2h |
| Cone | V = (1/3)πr2h |
Using a Measuring Tape and Calculator
This method is the most accurate and straightforward for measuring a quart of wood. Follow these steps:
- Gather your materials: You will need a measuring tape, a calculator, and a pen or pencil.
- Measure the length, width, and height of the wood stack: Measure the length in inches, width in inches, and height in inches. For example, if your stack is 24 inches long, 12 inches wide, and 16 inches high, write down these measurements.
- Calculate the volume of the wood stack in cubic inches: Multiply the length, width, and height to get the volume in cubic inches. In our example, the volume would be 24 x 12 x 16 = 4,608 cubic inches.
- Convert cubic inches to quarts: 1 quart equals 67.2 cubic inches. Divide the volume in cubic inches by 67.2 to get the volume in quarts. In our example, 4,608 cubic inches divided by 67.2 equals 68.6 quarts.
Here is a table to help you with the conversion:
| Cubic Inches | Quarts |
|---|---|
| 67.2 | 1 |
| 134.4 | 2 |
| 201.6 | 3 |
| 268.8 | 4 |
| 336 | 5 |
| 403.2 | 6 |
| 470.4 | 7 |

Using a Container
Fill a container of known volume with wood pieces until it is level with the top. The volume of wood in the container is equal to the volume of the container.
Using a Measuring Tool
There are various measuring tools available, such as calipers, rulers, and tape measures, that can be used to determine the dimensions of wood pieces. Calculate the volume by multiplying the length, width, and height of each piece.
Estimating the Volume
If precise measurements are not required, you can estimate the volume of wood using the following formula: Volume = (Length x Width x Height) / 5. This formula assumes that the wood pieces are roughly rectangular in shape and have an average density.
Tips for Accurate Wood Measurement
Determining the Volume of Irregularly Shaped Pieces
For irregularly shaped pieces, it is best to use the water displacement method. Submerge the wood piece in a container of water and measure the rise in water level. The volume of the wood piece is equal to the volume of water displaced.
Using a Volume Conversion Chart
For quick and easy conversions, refer to a volume conversion chart that provides the equivalent volumes of wood in different units, such as quarts, cubic feet, and cords.
Converting from Weight to Volume
If you know the weight of wood you have, you can use the density of wood to convert it to volume. The density of wood varies by species, so it is important to use the appropriate value for the wood you are working with.
Here is a table of average wood densities for common species:
| Species | Density (lbs/cubic foot) |
|---|---|
| Oak | 47 |
| Maple | 42 |
| Pine | 31 |
Calculating the Volume of a Stacked Pile
To measure the volume of a stacked pile of wood, determine the average length and width of the logs and then multiply these values by the height of the pile. For example, if the average log is 16 feet long and 12 inches wide, and the pile is 4 feet high, the volume would be (16 x 1 x 4) = 64 cubic feet.
Using a Laser Distance Meter
A laser distance meter can be used to quickly and accurately measure the volume of a stacked pile of wood. Simply measure the length, width, and height of the pile and enter the values into the meter. The meter will then calculate the volume for you.
