axle weight calculation

I have recently weight my tt tounge and got 650lbs using the bathroom scale method.

I think i recall seeing an equation using the ball distance from the axle and wheelbase to determine the weight applied to the axle without using wd.

If anyone knows the equation and would post it that would be much appreciated

Thanks

    Units of measure? lb for weight? inches for axle to ball? and inches for wheelbase?

    I don't know the equation, but I would assume you would first need to know the overall weight of the trailer from a scale to plug into the equation.
