No. 1 ppb = 1 ug/L or 1 microgram per liter. You can find conversion charts on the web (http://waterontheweb.org/resources/conversiontables.html) Yes, ng/mL is equivalent to parts per billion. While it is true that 1 ppb = 1 ug/L, it is equally true that 1 ng/mL = 1 ppb. They are the same sice 1 ng is 1/1000 of a ug and 1 mL is 1/1000 of a L. All that has changed is the units, but they remain equivalent.
No. Micrograms per ml is the same as milligrams per litre, which means parts per million (ppm). Regarding ppm, a gram and a ml are seen as equivalent, so there are a million micrograms in a gram (which is a millilitre). Now on the other hand, micrograms per litre is ppb.
Yes it is. Ppm means parts per million, and this assumes that a gram and a ml are equivalent. So parts per thousand would be microgram per microlitre. Then a million is microgram per millilitre.
if it is water 1000 ppm = 1 mg/ml
The two terms ppm and ml are not similar measures. PPM (parts per million) is a ratio and can apply to mass, volume, etc., while ml (milliliter) is a unit of volume - 1/1000 of a liter.
There are 0.8 milligrams in 800 micrograms.
50 micrograms per millilitre is the same as 50*500 i.e. 25,000ug per 500ml. 25000ug is 25mg. In every ml, there are 50mg, so you only need half of a millilitre.
Take 13.0 mL of the first solution ( 50 ug/mL) and dilute it up to 50.0 mL, you'll get the second solutionconcentration ( 13 ug/mL). Proof: 13.0 mL x 50 ug/mL of 1st = 50.0 mL x 13 ug/mL of in 2nd [Control: by units] 650 ug in 1st = 650 ug in 2nd
No. Micrograms per millilitre is exactly the same as ppm. There 0.5ppm is 100 times smaller than 50ppm.
1 ml of water weighs 1 gram, so if you are meaning microgram quantities, you would have parts per million. For example if you had 100 micrograms per ml, this would be the same as saying 100 grams per 1000 liters, which is the same ratio as 100 grams per million grams. Parts per million is expressed as ppm.
So when you talk about thousands of micrograms, you are talking about milligrams because you have 1000 micrograms in a milligram). Milligrams per litre is called parts per million also. This is ppm in short.
if it is water 1000 ppm = 1 mg/ml
The two terms ppm and ml are not similar measures. PPM (parts per million) is a ratio and can apply to mass, volume, etc., while ml (milliliter) is a unit of volume - 1/1000 of a liter.
How many ml equal 5 micrograms
300ng/ml is 300 micrograms per litre which is the same as 300ppb (parts per billion), or 0.3ppm (parts per million)
First, 100ug per ul is 100,000ug per ml. You want 100 micrograms per ml. Therefore you need to dilute 1 in 1000. If 250ul is your total volume, you need to take 0.25 microlitres of the stock.
There are 0.8 milligrams in 800 micrograms.
50 micrograms per millilitre is the same as 50*500 i.e. 25,000ug per 500ml. 25000ug is 25mg. In every ml, there are 50mg, so you only need half of a millilitre.

You cannot. Micrograms per centimetre cubed is a measure of density, with dimensions [ML-3] whereas micrograms is a measure of mass with dimensions [M]. They measure different things and elementary dimensional analyses teaches that you cannot convert between measures with different dimensions.
