Well, you've got to have something of known weight. To get a general idea you can use bullets, as they are almost always within less than .5gr of intended weight and many are within .1gr. This is really only a ballpark number though.

To get more exacting, 1 cubic centimeter of water weighs exactly 1 gram at 0 centigrade.

Basically, you need a check weight but you don't have to pay anywhere near $25. Here's one for less than $6, delivered.
