This web site says there are 30 grams in one ounce. But, everywhere I have looked says 28 grams. Which is the correct information? I am not sure which one to follow, and am concerned I will be studying the wrong conversion rates.

Laura, you are absolutely right. About once a month, I get an email about this. Honestly, I am glad when I get them, since it tells me that people are striving for perfection.
Here's the thing; When I started the site, I was on the fence about this very issue. After asking around and doing some research, I discovered that 90% of Pharmacy Tech books and programs rounded all irrational numbers up to the nearest whole number. By doing so, students have a much easier time memorizing them. And, the studying they're doing here is for the purpose of passing the PTCB or ExCPT exams. This site is meant to be a companion for students to use along-side an official program. Therefore, to avoid confusion, I also rounded those numbers up to match what the books and programs report.
Some examples are: 28.3495231 Grams are in 1 ounce (not 30)
