So - this is doing my head in...

0.1% of 300 grams is 0.3 grams - is that correct?

So is 30mg 0.3 grams or 0.03 grams?

Thank you in advance

Ok, so this is what I'm getting:
1 milligram = .001 gram
so
30 mg = .03 gram

0.1% of 300 grams is 0.3 grams - is that correct?

Yes, that is correct. To convert a percent to a decimal you move the decimal in the percent two places to the left. "Of" means multiply so: 0.001 x 300 = 0.3

So is 30mg 0.3 grams or 0.03 grams?

30mg is 0.03 grams. Milligrams to grams conversion you move the decimal three places to the left since there are a thousand milligrams in one gram.

I am not a mathematician, and I see @MellonFriend has given you the best answer, just a tip that might help in the future, when I need to convert anything (in your case, mg to gram) I just type it in google and a conversion page comes up With the result and where I can look up further measurements.

I do the same thing all the time! Even with temp! Converting Celsius to Fahrenheit… lately all my recipes give temps in Celsius.
