I know you mean well, but as he's talking cups & pounds, I have to assume he's here with us backward colonials.
Once we get the metric system, we'll be able to buy a 1Kg bag of anything... but right now, for sugar you get either 1 lb, 2lb, or 5lb. Most commonly 5lb from the supermarket for regular cane sugar.
I'd second the recommendation of using more malt rather than the sugar, if from a lower-end kit. Sugar will work, but malt will give a better beer.
