|---|---|
| Thickness (inches) | 2 |
| Width (inches) | 6 |
| Length (feet) | 8 |
| Number of pieces | 10 |
| Price per board foot | 5 |
| Board feet per piece | 8 |
| Total board feet | 80 |
| Total cost | 400 |

- A board foot is a lumber volume unit — 1 inch thick × 1 foot wide × 1 foot long (144 cubic inches) — the standard unit lumber is priced and sold by in many markets.
Frequently asked questions
What is a board foot?
A volume measurement for lumber — 1 inch thick, 1 foot wide, and 1 foot long (144 cubic inches). It's the standard unit lumber is priced by, regardless of a board's actual dimensions.
I just want the board feet, not the cost — is there a simpler version?
Yes — see the Board Foot Calculator for the same calculation without the cost fields.
How do I convert this to metric?
There's no simple metric equivalent since a board foot is a fixed imperial volume — for metric lumber, calculate volume directly in cubic meters (length × width × thickness) and price per cubic meter instead.
