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.
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
0.005 ug/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
Multiply the number in mg by 1,000 to get the same weight in micrograms (ug)
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.
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.
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.
400ppm
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
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.
100 ml 1 liter = 1000 ml 1 ml = 0.001 L
