MBF = 1,000 board feet — the M is the Roman numeral thousand. Sawmills, wholesalers and the lumber futures market all quote in $/MBF; this converter turns those quotes back into shop-scale numbers.
Retail yards talk board feet; the supply chain above them talks thousands. Mill price sheets, broker quotes, timber-sale appraisals and the CME lumber contract all run in $/MBF. The arithmetic is mercifully simple — divide by a thousand — but mixing the two units in one spreadsheet is how five-figure ordering mistakes happen, so this page exists to keep the decimal honest.
Say a mill offers 4/4 red oak at $900/MBF. That's $0.90/bf — against the $4–7/bf you'd pay at retail, which is the entire economic argument for buying green, in bulk, and drying it yourself. Whether that trade wins depends on your kiln access, patience and how you value your weekends; the math side, at least, is now settled. Tally the actual boards with the board foot calculator.
| $ / MBF | $ / bf | Feels like |
|---|---|---|
| $300 | $0.30 | softwood commodity territory |
| $600 | $0.60 | upper softwood / pallet hardwood |
| $900 | $0.90 | green domestic hardwood at the mill |
| $1,500 | $1.50 | kiln-dried hardwood, wholesale lots |
| $4,000 | $4.00 | where retail 4/4 red oak begins |
The three-decimal slide is also where unit confusion bites hardest: an MBF is a thousand board feet (volume), not a thousand feet (length) — a 2×6 quoted per MBF contains half as many sticks as a 2×12 buyer might assume. When a quote crosses your desk, anchor it to boards: at $900/MBF, a single 2×4×8 (5.33 bf) carries $4.80 of wood. Convert the whole order with the fields above, then sanity-check the per-piece price against the chart.
