Cord to Cubic Feet Converter

Convert cords of firewood to cubic feet and back using standard sizes plus customizable stacks. Perfect when a seller quotes face cords, half cords, or non-standard piles.

Select cord definition

Number of cords or fractional cords.

Computed as cords × selected cord size.

Enter actual measured volume.

Computed as ft³ ÷ selected cord size.

Active cord size: 128.00 ft³

How to Use This Converter

Enter the cords you are buying or selling, pick the cord definition that matches your supplier, and see the equivalent cubic footage immediately. You can also reverse the conversion: enter the measured cubic feet and the calculator tells you how many cords the stack represents.

Methodology

The tool multiplies the cord quantity by the cord size to get cubic feet, and it divides any cubic feet amount by the same cord size to convert back. That keeps the math transparent so you can verify every assumption.

What is a cord?

A cord measures a stack of firewood: 4 ft high × 4 ft deep × 8 ft long, which equals 128 cubic feet. Actual wood volume is less because of air pockets, but the stacked volume is the standard sellers quote.

Face cord vs full cord

A face cord is typically one-third of a full cord when logs are 16 inches long. That gives 42.67 ft³, but the amount varies with log length and how tightly the pile is stacked. Use the cord definition that matches your delivery for the most accurate comparison.

FAQ

1. My delivery looks short — how do I tell?

Measure the stack (length × height × depth) to get cubic feet. Then divide by the cord size you expect to identify how much of a cord you actually received.

2. Why is my face cord not exactly 1/3?

Different log lengths (14 in, 16 in, 18 in) and stacking techniques change the volume. The 42.67 ft³ number is the 16-inch ideal.

3. Can I convert to cubic meters?

Yes: 1 ft³ equals 0.0283168 m³. Multiply your cubic-foot result by that factor to get the metric volume.

Firewood tips

  • Ask which cord size your supplier uses.
  • Measure length × height × depth on delivery.
  • Seasoned wood stacks tighter than green wood.
