I am estimating each load to be far more than 1 BSH (British Standard Handful).
Your technical knowledge is commendable, but you made a critical mistake in your calculations, albeit a common one. You forgot to convert the units.
You'd have to use EASH (East Asia Standard Handful). The current conversion rate is around 2.54 to 1.
The whole exercise becomes much more feasible this way, if, of course, much less purposeful.
