Formula & Mathematical Methodology: Firewood Cord & BTU Formula

StackVolumecuFt = Lengthft × Depthft × Heightft
FullCords = StackVolumecuFt / 128
StackVolume_cuFt = Length_ft × Depth_ft × Height_ft; FullCords = StackVolume_cuFt / 128
  • stackLengthFt: Stack Length Ft (ft)
  • stackHeightFt: Stack Height Ft (ft)
  • logSplitLengthIn: Log Split Length In (in)
  • millionBtuPerFullCord: Million Btu Per Full Cord (MMBtu/cord)

Rounding: Physical package counts round up where appropriate; continuous measurements round to 2 decimal places.

Worked Example: Practical Benchmark: Firewood Cord & BTU

Convert woodpile dimensions (L × W × H) into Full Cords, Face Cords, and MBTUs.

  1. Enter your project dimensions, machining speeds, or recipe weights.
  2. Compute the governing equation: StackVolume_cuFt = Length_ft × Depth_ft × Height_ft; FullCords = StackVolume_cuFt / 128.
  3. Review the primary result, supporting dimensions, and 3 SVG visualizations.
Result: Computes Firewood Cord & BTU via StackVolume_cuFt = Length_ft × Depth_ft × Height_ft; FullCords = StackVolume_cuFt / 128.

Firewood Full Cord (128 cu ft), Face Cord & Heating BTU Calculator: inputs, method, and how to read the result

Convert woodpile dimensions (L × W × H) into Full Cords, Face Cords, and MBTUs.

Choose inputs for the case you are checking

The defaults are illustrative. Replace them with values for your case and keep the units shown beside each field.

  • Stack Length Ft: Stacked woodpile length in feet.
  • Stack Height Ft: Stacked woodpile height in feet.
  • Log Split Length In: Individual split firewood log length in inches (16" standard face cord).
  • Million Btu Per Full Cord: Heat content per seasoned cord in Million BTUs (24–28 hardwood, 15–18 softwood).

What the calculation includes

With the default values shown, Volume in Full Firewood Cords is 0.67 full cords. The calculation follows Firewood Cord & BTU Formula; the formula and variable definitions above show how the inputs combine.

One-input check: With the other defaults held constant, changing Stack Length Ft from 16 ft to 18 ft changes Volume in Full Firewood Cords from 0.67 full cords to 0.75 full cords. This is a comparison inside the calculator's stated model, not a prediction.

Where to use caution

  • Uses standard North American & metric trade dimensions, Machinery’s Handbook formulas, and culinary weight ratios.
  • Verify local municipal building codes, tool manufacturer limits, and food-safety time/temperature tables before execution.

Scope: Trade, Shop & Culinary Science Reference Standard Check the assumptions and limitations against your situation before relying on the estimate.
