Metric Equivalents for Various Units of Measure

1 acre                         = 0.404686 hectares
1,000 acres              = 404.686 hectares
1 board foot              = 0.00348 cubic meters
1,000 board feet     = 3.48 cubic meters
1 cubic foot               = 0.028317cubic meters
1,000 cubic feet      = 28.317 cubic meters

Although 1,000 board feet is theoretically equivalent to 2.36 cubic meters, this is true only when a board foot is actually a piece of wood with a volume 1/12 of cubic foot.  The conversion given here, 3.48 cubic meters, is based on the cubic volume of a log 16 feet long and 15 inches in diameter inside bark at the small end.
