Yes, it also equals 1 g/m³

Hi i want to convert mg/ml into mg/L (PPM) or ug/ml. I have 10 mg/ml standard solution of a compound and i would like to dilute the solution into concentration range of 21 ug/ml-39 ug/ml?
Thank you

If I have a stock concentration that says 1 mg/ml and I need a concentration of 0.5 ug/ml, how do I calculate the volume I need to use of the stock concentration. Does it need to be diluted?

Hi guys!
Sorry im confused about the conversion.
Im looking at converting 50 pg/L(ug/L) into ng/ml.
Can you please help?
Cheers

Do you mean picograms or micrograms? They differ by a factor of 1 million.
50 µg/L = 50 ng/mL
50 pg/L = 50 fg/mL

1000 mL = 1 L
1000 ng = 1 µg
1000 pg = 1 ng
1000 fg = 1 pg
You just need to memorize all the metric prefixes or have a table handy

Hi all, i wonder if someone can help.

I am using an alcohol measuring device and the read out is xxx ug/100ml and i need to convert to mg/L.

Do i divide the xxx readout by ten to convert into mg/L????

If anybody can help it would be much appreciated.

Thanks in advance

xxx µg/100 mL x 1000 mL/L x 1 mg/1000 µg = x.xx mg/L
You need to divide by 100, not 10.

Another way to visual, divide by 100 to get µg/mL, then multiply both numerator and denominator by 1000 (which cancel numerically) to get mg/L.

in my class we have 3.66g/l of a liquid in a 1liter flask and now we are figuring out how much can we put if we want to use a 100ml flask. so i have to convert 3.66g/l to ml... i believe that im highly overthinking this. help

The 3.66g/L is the concentration of something in the liquid, but I assume you have a liter of liquid in the liter flask. One liter = 1000 milliliters, 100 mL is 0.1 L. If you were mixing 100 mL, you would use
3.66 g/L x 0.1 L = 0.366 g (or 366 mg)

how much do i need to reconstitute blasticidin S, 50 mg powder to a 15ug/ml solution. MW: 458.9 thanks!
