Help with units of mass in English

[coffeebeany]

Since english is not my native language I was wondering if anyone could help me with the information of the units of mass that I read in a book. It says "The amount required is 10 gm." Does gm mean grams or milligram?
Thank you in advace.

gm = gram
mg = milligram

 

[coffeebeany]

gm = gram
mg = milligram

thank you!

Very strange to see gram contracted to gm. But that does seem more likely than milligram, which would be mg.

I thought the same and wanted to make extra sure. Where I m from we use mg for milligram and gr from gram. So thank you !
