mg/ml to ng/l

Forum rules
Dear convert-me.com forum visitors,

Our forum has been available for many years. In September 2014 we decided to switch it to read-only mode. Month after month we saw less posts with questions and answers from real people and more spam posts. We were spending more and more resources cleaning the spam until there were less them 1 legitimate message per 100 spam posts. Then we decided it's time to stop.

All the posts in the forum will be available and searchable. We understand there are a lot of useful information and we aren't going to remove anything. As for the new questions, you can always ask them on convert-me.com FaceBook page

Thank you for being with us and sorry for any inconveniences this could caused.

mg/ml to ng/l

by Bob » Wed Feb 15, 2006 10:28 pm

Here's one for you:
I have a 100 mg/ml stock solution and I need to create solutions that are 10 ng/l
50ng/l
500ng/l

I don't want to make up a litre of each, just a small amount, say 10 ml. How many ul of the stock solution do I need to use in each case?

I also have some other stock solutions if they are of any help:
10ng/ul
1000 mg/ml
