Cords to Tons Calculator

Convert cord measurements to tons (pulpwood or firewood) based on wood density

Input Parameters

Default for softwood (e.g., pine, fir): 40 lbs/cu ft

Calculation Results

Calculation Formula

Volume (cu ft) = Length × Width × Height

Weight (tons) = Volume × Density / 2000

Where:
Volume = Total volume of wood in cubic feet
Density = Weight per cubic foot of the specific wood type
2000 = Number of pounds in one ton

Learn how to use the Cords to Tons Calculator calculator and its working principles

How to Use This Calculator

  1. Enter the cord length in feet (typically 8 feet)
  2. Enter the cord width in feet (typically 4 feet)
  3. Enter the cord height in feet (typically 4 feet for a full cord)
  4. Enter the wood density (pounds per cubic foot) if different from the default (40 lbs/cu ft)
  5. Click the "Calculate" button to determine the volume and weight

Understanding Cord Measurements

A cord is a unit of firewood volume measuring 8 feet long by 4 feet wide by 4 feet high (128 cubic feet). However, firewood is often sold by "face cord" (just 8' x 4'), so always clarify what measurement is being used.

Wood Density Reference

  • Softwoods (pine, fir, spruce): ~40 lbs/cu ft
  • Hardwoods (oak, maple, ash): ~42-50 lbs/cu ft
  • Softwood chips/scraps: ~30-35 lbs/cu ft

Example Calculation

If you have a full cord of pine wood with a density of 40 lbs/cu ft:

Volume = 8 ft × 4 ft × 4 ft = 128 cu ft

Weight = 128 cu ft × 40 lbs/cu ft = 5120 lbs = 2.56 tons
