I happened to have a half-cup measure at hand as well as a gram scale, so I weighed a half-cup of the powder => 120 grams. Nine half-cups gives 1080 g, which is quite close to the 1100 grams my 11 liter cooling system would take. Now everyone else knows a half-cup of citric acid is 120 grams and can scoop out accordingly. Craig
