두께 × 너비 × 길이로 보드 피트와 총 비용을 계산하세요. 여러 항목 쇼핑 리스트, 수종별 프리셋, 공칭 치수 대 실제 치수 비교도 제공합니다.

보드 피트: BF = 두께(in) × 너비(in) × 길이(ft) / 144, 여기에 수량을 곱합니다. 1보드 피트는 1×12×12인치 크기(144in³)에 해당합니다.
공칭 치수 vs 실제 치수: "2×4" 목재는 대패질 후 실제로는 1.5"×3.5"이고, "1×6"은 0.75"×5.5"입니다. 거친 제재목이나 하드우드에는 실제 을(를) 선택하고, 공칭 규격 소프트우드에는 이쪽을 선택하세요.
미터법: mm/m 단위로 입력한 치수는 자동 변환됩니다 (1인치 = 25.4mm, 1피트 = 0.3048m). 1BF ≈ 0.002360㎥.
A board foot is a unit of volume, not of length: 144 cubic inches, the volume of a piece one inch thick, twelve inches wide and twelve inches long. From thickness in inches, width in inches, length in feet and a quantity, the standard hand rule is thickness × width × length(ft) ÷ 12. The page keeps a running total for the whole list and reports board feet, linear feet, cubic metres at 0.002360 m³ per board foot, and total cost at your dollars-per-board-foot rate.
Each row carries its own species, dimensions, quantity and price. Choosing a species overwrites that row's price with a preset — SPF (2-by) at 1.80, Pine 2.50, Cedar 4.00, Maple 6.50, Oak 7.00, Cherry 9.00, Mahogany 11.00, Walnut 12.00 — and you can type over it immediately. The Lumber size selector names the two conventions, Actual dimensions and Nominal, but the arithmetic always uses the numbers you type, so enter planed sizes: 1.5 × 3.5 for a 2×4, 0.75 × 5.5 for a 1×6.
This is a volume and price sheet, nothing more. There is no waste, defect or kerf allowance, so a rough-sawn hardwood order usually needs 15 to 30 percent added on top for cupped boards, sapwood and cutting losses. Hardwood is normally sold in quarter thicknesses — 4/4 is one inch rough, which surfaces down to about 13/16 — and the tool cannot know which you are being charged for. Sales tax, delivery and minimum-order charges are not included.
Using the planed actual size of 1.5 by 3.5 inches, it is 1.5 × 3.5 × 8 ÷ 12, which is 3.5 board feet. Entering the nominal 2 by 4 instead would give 5.33 board feet, which is why planed dimensions matter.
Linear feet just counts length and ignores how thick or wide the stock is. Board feet is volume. The result panel shows both, because lumber yards price hardwood by the board foot but sell dimensional softwood and trim by the piece or linear foot.
Enter actual, planed dimensions. A 2x4 measures 1.5 by 3.5 inches, a 1x6 measures 0.75 by 5.5 inches, and a 4x4 measures 3.5 by 3.5 inches. Nominal names describe the rough size before drying and surfacing, and overstate volume noticeably.
The tool does it for you using 1 board foot equal to 0.002360 cubic metres, shown next to the total. If you enter metric instead, switch Units and type thickness and width in millimetres and length in metres; they convert at 25.4 and 3.28084.
Yes. Add a row per species with the + Add row button; each row keeps its own dollars-per-board-foot price, and the detail table breaks out board feet and cost line by line while the summary shows the combined total for the whole order.
