    Converting sq. feet to board feet??

    So a 3/4" oak piece of wood that is 12" long and 12" wide is 1 board foot, correct?

    So would 23 square feet of 3/4 oak be the same as 24 board feet of 3/4" oak?

    Nope, a 4/4 12x12 board would be a board foot.

    To get board feet multiply L x W x Th and divide by 144.

    Hoyt,

    Not really. They sell 3/4" stock AS 1" stock when it's faced. But you get 3/4".

    Try this board feet calculator

    Board feet is: Length X Width X thickness, and square feet is Length X Width... so the only difference is the thickness... as long as the boards are 1" thick (4/4) then the measurements would be the same... if the board has been planed to 3/4", it is still considered a 4/4 board i.e. 1" board....

    So 23 board feet is the answer....

    ... Mark.. I think we fell on this at ed-zakerly the same time...

    Hoyt,

    The deal is like this. If you buy stock that's already 3/4", leave it in your workplace for 2 weeks to acclimate, look at it, most are cupped or bent, by the time you face joint and plain them, maybe you're lucky to have some that are 5/8".

    So plan on buying 4/4 stock that really is 4/4 and maybe you stand a chance of winding up with 3/4" boards.

    Most places will charge you for 4/4 and sell you 3/4" boards. You have to "watch" what you buy. I've been learning the hard way.

    Howard,

    3/4" thick finished stock is 4/4 ( not one inch, but four quarter) rough. You are paying to have it planned down to a finished thickness of 3/4". If you need a finished peice that is 1" thick, you need to buy 5/4 (five quarter) rough stock and mill it down to 1". They are not really charging you for 4/4 and only giving you 3/4. Hardwoods are always sold by the quarter. There is a difference between 4/4 (four quarter) and 4/4" (one inch).

    The use of 3/4 and 4/4 get a little mixed up, don't they. I buy from wood dealors, that's all they sell, in Lancaster County, Pennsylvania. There 4/4 or 5/4 is 4/4 and 5/4. They aren't planing it for you and you are getting what you pay for. This is the way hardwood is supposed to be sold, not by nominal dimensions.

    You will find people dealing in all their lumber this way but hopefully the only hardwood dealors doing this have already planed the wood for you.

    RE: Converting sq. feet to board feet??

    I never buy it milled so correct me if I'm wrong.
    1" rough stock after milled is usually 3/4"
    (13/16" actually, that's the standard)
    Most people "count" 3/4" thick stock as 1" thick.
    If you count 3/4" stock the same as 1" stock then "Yes"
    12"x12" is one board foot.
    Technically it's really 3/4 board foot but everywhere I've
    seen selling 3/4" milled stock counts it as though it
    was 1" thick. I guess that's a "nominal" dimension.
    But on the otherhand, if you buy it thicker like 5/4 (1 1/4")
    then they always count that.
    12" x 12" x 1 1/4" = 1.25 board ft.
    Doesn't seem fair (LOL)
