Be sure to get a set of calibration weights at 1/2/5/10/20 etc. grams. Cheap scales are cheap -- and the readings sometimes drift with temperature and battery voltage. A set of weights will keep your scale honest.

You don't need to go hog wild on the quality of the calibration weights - a cheap set will do the job for what you're measuring.

Side story -- I used to work at a company that had a chemistry lab that analyzed metal purity, assay of acid solutions, etc. Their calibration weight set was made out of 24K solid gold so the weights wouldn't oxidize over time, and could be acid washed from time to time to eliminate surface contamination. They were 100 miligrams, 1 gram, 2 gram ... up to 25 grams. The "whole set" weighed about 1 troy ounce and was made sometimes in the 1950s. They looked brand new in 1990 when I was there. The scale they used to weigh things was accurate to 0.00001g (0.01 milligrams) !
