About Firewood calculator
Enter the stacked pile: length along the wall, height, and depth equal to the log length. Stacked volume is length times height times depth. A full cord is 128 cubic feet, the classic 4 by 4 by 8 foot stack, about 3.62 cubic meters. Steres are the same number as stacked cubic meters.
A face cord, or rick, is 4 feet high by 8 feet long by the log length. It equals one third of a cord only when the pieces are 16 inches. This tool divides your stack by that face-cord volume, so a 12-inch or 24-inch depth does not pretend to be a third cord.
Weight uses a solid-wood share of the stack, default 65 percent, times a species density. Seasoned planning densities are oak 720, birch 640, maple 680, pine 450, and mixed 600 kilograms per solid cubic meter. Green wood multiplies that weight by 1.4. Match a supplier ticket if you have one.
Nothing is uploaded. Empty, zero, and oversized stacks are rejected. This is a stacked-wood order, not a gravel, mulch, or grass-seed calculator.
How to use it
- 1Choose meters or feet, then a stack or a known stacked volume.
- 2Set length, height, and log depth, or paste the stacked volume.
- 3Pick species, seasoned or green, and a solid-wood share if the stack is loose.
- 4Review cords, face cords, steres, weight, and optional cost, then copy the order.
Frequently asked questions
- How is a cord of firewood calculated?
- Stacked volume is length times height times depth. Full cords are that volume divided by 128 cubic feet (about 3.62 cubic meters). Face cords use 4 feet by 8 feet times the log depth, so they change with piece length.
- Is a stere the same as a cubic meter?
- Yes for stacked firewood. One stere is one cubic meter of stacked wood, including the air gaps. It is not a solid cubic meter.
- Why is the weight only an estimate?
- Stacked wood is partly air. The default solid share is 65 percent. Species density and a green-wood factor of 1.4 are planning figures, not a moisture-meter reading.
- Does the calculation leave the browser?
- No. Stack sizes, species, prices, and the order summary stay on your device.
