Did an experiment. White sugar is served with a ceramic spoon commonly used at home. The filling quantity is based on shaking the spoon gently after filling and the sugar does not fall out of the spoon. A container of 100ml can be filled with about 5 spoons, and the density of white sugar is about 0.9 tons /M3, which is a little smaller than that of water (the density of pure sugar without cracks is 1.5879 tons /m3), so the white sugar of a ceramic spoon is about 1.5879 tons /m3.
