Lets see, have a brew first, now where is that calculator? Oh found another brew, lets see what is that formula again? Honey where is the tape measure? Man that is a lot of work have another brew. Man this don't make sense - Honey would you run the unit down to Flying J and scale it for me while I try to figure this formula out?
And pick another case of Bud on the way home.
I'm sorry, that might be good information but still seems a lot simpler to just go to the scales at your local truck stop. Some math experts might appreciate the formula and process.
