- Raw Volume 128.00 ft3
- Adjusted Volume 115.20 ft3
- Full Cords 0.9000
- Face Cords (piece 16 in) 2.7000
Reference: 1 full cord = 128 ft3 (4×4×8). Face cord volume = 32 ft2 × piece length (ft).
Example Data
| Scenario | Dimensions | Efficiency | Adj Volume (ft³) | Full Cords |
|---|---|---|---|---|
| Full Cord | 8×4×4 ft | 90% | 115.20 | 0.9000 |
| Face Cord 16" | 8×4×16 in | 90% | 0.27 | 0.0021 |
| Face Cord 12" | 8×4×12 in | 90% | 0.20 | 0.0016 |
| Half Cord | 8×4×2 ft | 90% | 57.60 | 0.4500 |
| 3/4 Cord | 8×4×3 ft | 90% | 86.40 | 0.6750 |
Formula Used
A full cord is defined as 128 ft3 arranged as 4 ft × 4 ft × 8 ft. The volume of your stack is
V = L × H × D (in feet). To account for air gaps and imperfect stacking, we apply an efficiency factor
E (0–1): Vadj = V × E. Full cords are then
Cords = Vadj ÷ 128.
For a face cord (also called a rick), the stack is 4 ft high by 8 ft long and as deep as the piece length.
Its volume is 32 × piece_length_ft. The number of face cords is
FaceCords = Vadj ÷ (32 × piece_length_ft).
Convert inches to feet by dividing by 12. Examples: 16 in = 1.333 ft; 24 in = 2 ft.
