Electronic gram scales are available for only $10 to $15!
Search for "gram scale .01" on amazon.com. Here they are:

Cost cannot be an objection at such a low price, and it solves all measurement issues. Weighing powders is more accurate. I prefer to weigh liquids as well, as it's more accurate and convenient.
