hey thanks thatll work if i had excel on my computer but im actually looking for the formula not a computer that does it for you. ive seen it somewhere but i cant find it anymore

 

just look at the formula on the spreadsheet?

 

it's pretty simple math. you should be able to derive the formula with a lil work. or just copy it from the spreadsheet.

also, if you set up a gmail account, you can use google spreadsheet program to view and use the spreadsheet.

 

thanks guys the reason that wouldnt work is i dont have excel on my computer. but i found it in the best welds thread so im set. thanks for the help guys
