About BoardFeetMath

BoardFeetMath covers the units wood is actually sold in: board feet, sheets, cords and pounds. Lumber yards, firewood sellers and sawmills each price differently, and the calculators turn your measurements into their unit so you can compare and check a price before you pay.

Who runs BoardFeetMath

BoardFeetMath is written and maintained by Hassan Nawaz (Publisher).

How the numbers are checked

The calculators use standard lumber trade measures (the board foot and the 128 cubic foot cord), the Doyle log rule, and green wood weights based on the USDA Forest Products Laboratory Wood Handbook. Every tool runs in your browser, and each page shows its formula so you can check the math yourself. Before publishing, every calculator is tested against worked examples. When a source changes or a reader reports a problem, the page is checked again.

Limits

Sizes, board feet and cord volumes follow standard trade measures. Prices and local rules for firewood and log scaling differ, so confirm with your seller.
