To convert mmol/l to mg/l
Multiply mmol/l with 18 you will get mg/l.

A mole, or mol of something is the weight of a precise number of atoms or molecules, called Avagadro's number. This is the atomic or molecular weight.

1 mol of lead nitrate is the weight in grams of 6.0221415 10 molecules.

It will be a LOT more than 18.
18g is the weight of 1 mol of water (H2O).

A 1mol/L (1M or 1molar) solution has 6.0221415 x 10 molecules per litre, and is in g/L
A 1mmol/L (1millimolar) solution is 1000 times more dilute, and there are 1000mg in 1g.

So to go from mmol/L to mg/L, multiply by the molecular weight.

To go from mg/L to mmol/L divide by the molecular weight.

Lead is poisonous, particularly in solution. If you are really dealing with these solutions, is it possible to get the help of someone who is trained in the use of chemical poisons?

Hi, If post #6 doesn't answer your question, please can you provide information about what you are trying to do, exactly?

Regarding the number '18' in this forum.
It appears in much literature surrounding the conversion of mmol/L - especially for blood glucose.

I found a diabetes article today that uses the number 18 as a conversion tool, on a UK diabetic website. I was trying to find a simple explanation for mmol/L for a student nurse whom I am mentoring just now. As usual I have become totally side tracked.

I would find it interesting to discover where the '18' originates - can investigate 'links' myself, if any available. Thank you.
