# Cord of Wood Calculator

This **cord of wood calculator** will help you figure out how much firewood you've got stacked up in the yard using the standard (US and Canada) unit - the cord - as well as the smaller **face cord of wood** unit. Give this tool your local firewood price per cord, and it will also let you know how much that stack of firewood is **worth**.

Don't worry, we'll also tell you exactly **what the dimensions of a cord of wood** are if you're unfamiliar with this unit of volume.

## What is a cord of wood? How much is a cord of wood?

OK, so what is a cord of wood, exactly? It's a unit of volume that is used to measure the amount of firewood and pulpwood in a stack of uniform lengths, with minimum gaps between the logs. One **full cord** is **8 feet** (2.44 m) long, by **4 feet** (1.22 m) wide, by **4 feet** (1.22 m) high. These dimensions gives a total volume of **128 cubic feet** (3.62 m³).

The name "cord" probably derives from the piece of cord or string that was used to measure stacks of logs.

## How to calculate a cord of firewood?

The **formula** to convert a set of length, width, and height measurements of a stack of wood in feet to the number of cords of wood is as follows:

`number of cords = (length (ft) * width (ft) * height (ft)) / 128 ft³`

or, if you wonder how much is a cord of wood using SI units (meters):

`number of cords = (length (m) * width (m) * height (m)) / 3.6246 m³`

Let's say we measure a big stack of wood in a forest that is 15 feet long (4.57 m), 6 feet deep (1.83 m) and 7 feet high (2.13 m). Plugging in those numbers into the formula would give:

`number of cords = (15 * 6 * 7) / 128 = 4.9 cords`

## What is a face cord of wood?

If the stack consists of **standard 16 inch long logs**, and the stack is only one log deep, we call it a **face cord of wood**. So a face cord is **8 feet** (2.44 m) long, **16 inches** (40.6 cm) deep, and **4 feet** (1.22 m) high, which is about the amount you'd see stacked up against a log cabin, ready for a long winter. A face cord is **one third** the amount of wood in a full cord.

The formula for a face cord of firewood is very similar to the cord formula, except the width is fixed to 16 inches (1 ⅓ feet):

`number of face cords = (length (ft) * 1 ⅓ (ft) * height (ft)) / 42.67 ft³`

or, equivalently in SI units:

`number of face cords = (length (m) * 0.406 (m) * height (m)) / 1.208 m³`

For example, outside our log cabin we stack some standard length firewood, whose length is 7 feet (2.134 m), and height is 4 feet (1.219 m). The number of face cords is:

`number of face cords = (7 * 1 ⅓ * 4) / 42.67 = 0.875 face cords`

## How to use this cord of wood calculator?

The cord of wood calculator will guide you step-by-step to determine what is a cord of wood for you. Just follow the below points:

- If you have the
**length**,**width**, and**height**measurements, enter them into the**first three rows**of the calculator. If you have the measurements in another unit, other than the one displayed, go ahead and click on the unit to change it to a unit that matches your measurement. - Alternatively, if you already know the volume, you can enter it directly into the
**volume**field of the calculator. - The calculator will then display the number of full cords of wood, along with giving the amount as a percentage of one full cord.
- For a
**face cord**, the calculator will accept any width measurement, but to be correct, change the units of the width row to inches and enter the number 16. - The calculator will then display the number of face cords of wood, along with the amount as a percentage of one face cord.
- To show the total cost of your stack of wood,
**enter a price per cord**.
