You are right that KCl should be measured by weight if you want to do it properly. But I used measuring spoons to measure it, not a scale which would have been a lot more tedious. Thus I really mean 2 mililiters which was roughly 3.2g of KCl (at least with my crystals) which corresponds to roughly 1600 mg of K. For comparison, my typical potato meal was 500g of potatoes which corresponds to 2700 mg of K.
