It is a measure of density.
1 mg/kg = 1 ppm 1 mg = 1000 micrograms (ug) so 10 ug/kg = 0.01 mg/kg = 0.01 ppm
They are the same: 1 cubic cm = 1 mL
1 US gallon = 4408.9 ml.
divide by 1000 Reason: one cubic mm is 1/1000 the size of 1 ml
1 liter = 1,000 ml 0.1 liter = 100 ml At 1 ml per minute, 100 ml takes 100 minutes. That's 1hour 40minutes.
0.005 ug/ml
1 nanogram (ng) = 0.001 microgram (ug). 1 milliliter (mL) = 0.01 deciliter (dL) (ng / mL) * (ug / ng) * (mL / dL) = ug / dL Therefore, 1 ng / mL = (1 ng / mL) * (0.001 ug / ng) * (mL / 0.01 dL) = 0.1 ug / dL
To convert from micrograms per gram (ug/g) to nanograms per milliliter (ng/mL), you need the density of the substance in grams per milliliter. Once you have the density, you can multiply 7 ug/g by the density to convert to ng/mL because 1 ug = 1000 ng and 1 g = 1 mL.
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
1 mg = 1,000 ug 1 mg per Liter = 1,000 ug per Liter. 1 mg per Liter is 1,000 times as concentrated as 1 ug per Liter.
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.
To convert milligrams (mg) to micrograms (ug), you need to multiply by 1000 because there are 1000 micrograms in a milligram. To convert milliliters (mL) to microliters (uL), you also multiply by 1000 because there are 1000 microliters in a milliliter. So, to convert 40 mg/mL to ug/uL, you would multiply by 1000 x 1000 = 1,000,000. This means 40 mg/mL is equal to 40,000 ug/uL.
2000 µg are 2 mg
You need to know the "molar/molecular weight" (MW) of what ever it is you are measuring. The molar weight is the mass of one mole (6.02214×10^23 copies) of a substance. (By the way 6.02214×10^23 is known as Avagardo's number). So if one mole of a substance weighed 1 g, then in 1 ug there would be 6.02214x10^20 copies. Further, what you do is this: copies/ml = ug/ml x (MW/1000) x L MW is generally given as g/mol thus you need to divide by 1000 go get ug/mol. L is Avagardo's number.
You cannot associate weight and volume directly without knowing density. If we assume density is 1 gram per ml, 2ug (micrograms) is going to equal 0.000002ml. This is because a gram will be a ml, a mg will be .001g and a ug is 1000 times smaller than mg
100 ml 1 liter = 1000 ml 1 ml = 0.001 L
The absorbance data correlates to the initial protein concentration in ug ml in one way. It breaks down protein in the stomach by the action of the stomach acid.
