Default uM into ug/mL

Hi everyone!!

This is my first time in this forum, so hello again to everybody!

I need the formula to convert microMolar into micrograms per mililiter. Example: how many ug/mL is 10 uM of A? (Molecular Weight of A= 300)

thank you and have a nice day!

Hi there,
Don't know if you still need this but the answer is:

A molecular weight of 300 means a 1M solution is 300 grams in 1 Litre
So
1M = 300g in 1 Litre
1mM = 300mg in 1 litre
1uM= 300ug in 1 litre

Multiply by ten to get a 10 uM solution ie 3000ug in 1 litre
Divide by 1000 to get the amount in mls ie 3 ug in 1ml

So 3ug/ml is the equvilent of 10uM for a molecular weight of 300

Hope that makes sense!!

If 0.14g/mL (1.4 micrograms per millilitre) is the concentration of the drug of interest, then that is your content. What units do you need the answer in?

this is not rite is it? i mean how can
1M = 300g in 1 Litre
1mM = 300mg in 1 litre
1uM= 300ug in 1 litre

all give you 300 as its value?

also how can you convert bk from ug/ml to uM for example, 10ug/ml how much will it be in mM?

Note in the original post that the molecular weight (also the molar mass) was given as 300. More generally, 1 M means 1 mole per liter, and you need the molar mass to convert to grams per liter.

ah! i see now... wud it be right to assume tht molar mass is same as molecular weight? if so, then how will u convert 10ug/ml to mM if the molecular weight is 6121?

Yes, the molar mass in grams per mole is numerically equal to the molecular weight in daltons, or unified atomic mass units (which are the same thing). For molar mass of 6121 g/mol

10 g/mL is also 10 mg/L
10 mg/L x 1 mol/6121 g = 1.63 mol/L = 1.63 M
