I was asked today why no South African timber outlets understood the measurement known as Board Feet (foot)its very much an American and Canadian measurement,they are on their own with this one but we still buy our bulk lumber in packs that may well be measured in board foot dimensions,we just need to know how to calculate to sizes that make some sense? ( i just love these questions)

I enjoyed yr post about 'board feet'. I used to work for CCAL ( Christensen Canadian African Lines) whose ships traded between St Lawrence Canada and Sa. We carried a lot of timber ( oak / beech ect ) in breakbulk form. Ticktin timbers was one of the Cape Town receivers. Now everthing seems to move in containers.
cheers

Lumber - How do you calculate board feet?
In: Building and Carpentry, Flooring.
Answer
Though "board foot" sounds a measurement of area it is actually a measurement of volume. 1 board foot equals 144 cubic inches of wood.
Length x Width x Thickness = Board Feet
Therefore a board that is 12 inches x 12 inches x 1 inch is 1 board foot.
But so is a board that is 12 x 6 x 2
However, you must take into account the fact that all lumber is actually a different size than it says it is. A 2 x 12 is actually 1-1/2 by 11-1/2. So instead of a board foot of 1 x 12 being 12 inches long, it would be:
144 / (3/4 x 11-1/2) or 13.22 inches long.
