log price to scale question

[gww]

Out of curiousity I used the tool box to check the price of a log.
I put $300 as the 1000 bf price.  What I don't understand is the scales.  When I put international scale in the doyle is the lowest board foot for a log but has a higher price for the same log that is scaled as international.  Could somebody explain what is going on in laymans terms.  Just pretend you are trying to make the dumbest guy in the crowd understand.
Thanks

doyle scale is accurate at about 20in below that the sawmill will have more boards than the scale says it should. International is more accurate thru and thru but doyle in this area is what everybody uses. The thing that matters is whatever scale there using the price of the log comes out the same. Doyle scale for small logs scales low bdf so it helps the mill on low productivity, high by product. Theres dscussions on ths on the forum

Killa....
But on the tool the log did not come out the same when it showed the price of the other scales.  By the way, If this is your third post and I haven't said welcome yet then "welcome to the forum".

the way the calc works is showing the different prices per thousand to make the 1 log bring the same money
if you pull the calc back up it will show doyle has the lowest bdft but the highest price per 1000bd, scribner is in the middle with both price and bdft and international has the highest bdft but the lowest price per 1000bdft this is really handy for someone like me who is used to doyle and was quoted a price on international scale to see what the price i would be paying doyle. on a 14" 8' log was about 20 bucks at 300 per 1000 international and the same log at the same about 20 bucks worked out to 408 per 1000 doyle  using the log value calc if you change scales you have to change the price per 1000 to what the  calc told you at the bottom  ;)  
so by that calc i can tell you i am paying 450 per 1000 doyle, or 368.85 scribner, or 330.88 international  for good tie logs but the way they are cutting us back that may change on any monday from here on if i have to change my price i always tell them when they get their check on friday what the price will be starting monday. if its not changing i just dont mention it  never change the price mid week ;) my price has been the same for 2 yr

I read that three times but don't quite get the fairness of it.  It is counter intuitive for less board foot to bring a higher price.  The one log brought more money on the doyle scale and fewer counted board feet and more overall for 1000 board foot.  I am tire now and will try again tomorrow.  I do thank you for your efforts and may even get it tomorrow.

You're thinking of board footage like that in a sawed board.  Log scales are an estimate of the footage in a log.  Since they use different mathematical calculations, the volume comes up different.  The log is the same, and the calculator simply tells you the needed value in each scale to get the same price for the log.  Some mills buy on International, some on Doyle.  Who pays the best price for a given log?  If you're buying logs, what scale are you going to use?

Sandsawmill gave an excellent response.

gww try thinking of it as liters vs gallons  or kilometers vs miles     the numbers are different but the amount is the same (if you do the conversion right ;D )

thanks ron

I am guessing this is why I did bad in school.  I know you guys are talking english and don't have a clue why I am having a mental block.  It doesn't matter too much because I do know the price differances now and how it works even if I can't figure the why.  So from a practical sence I will know what is happening.  Some time later when I am not even trying the rest of it might pop in my brain.  Thank you guys for the help.
