I dont know weight measurements yet. I use mostly like 0.5% and up...say this recipeThere are lots available which are very small. I have used one like this below for a very long time; didn't cost much either; uses AA batteries. The only thing I will do differently the next time I purchase a new scale, is get one that is a 300g X 0.01g. The one I have now is a 500g X 0.01g; it has a tough time measuring 0.01g to 0.05g sometimes; there are some flavorings which I want no more than 0.03g in the mix. This is when I just have to assume 2 to 4 drops will be sufficient for the mix.
The size is roughly 6 inches X 6 inches.
