You cannot. The problem here is you have weight per area and you want to convert to weight per volume. You need a third dimension to the area to calculate this.
(Micrograms per litre)/(gram molecular weight of solute) = (micromoles per litre).
The formula is no. moles is mass over molecular mass. If you multiply micromole by molecular mass you get micrograms. Then you have to divide by 1000 to convert per litre to per millilitre.
.001mg
31.1 (milligrams per liter) = about 1.817 grains per US gallon.
You cannot. Milligram (not miligram) and kilogram are measures of mass whereas a litre is a measure of volume. So mg per kg is a pure ratio - with no units whereas the second is a measure of density with units of mg per litre. You cannot convert from one to the other without additional information.
They are the same thing. You have to divide to convert micrograms to milligrams. You have to multiply to convert per litre to per metre cubed. these cancel out.
0.461 milligrams per litre
No. Micromolar is a measure of micromoles per liter, not micrograms per liter. To convert between micrograms and micromoles, use the molar mass of the substance.
In order to convert between milligrams and micromoles, one has to know the molar mass of the substance in question, then simply convert from grams to moles. As an example, let's assume that the measurement is that of oxygen, or O2, and that there's 10 milligrams per liter. First, divide by 1,000, to convert to grams, in this case, .01 grams. Then, divide this amount by the molar mass, which represents the number of grams in a mole. For O2, this is approximately 31.9988. This gives us a result of around .0003125 moles, or 3.125 x 10^-4. Then, we multiply by 1,000,000 to convert from moles to micromoles. The end result is approximately 312.5 micromoles in the liter.
Firstly there is no such thing as litre cubed. It is just litre. ppm means milligrams per litre, so you have 10,000 milligrams per litre. This is 10,000,000 micrograms per litre.
You don't. The milligram is a unit of mass. The liter is a unit of volume.
note: 1 miligrame=0.001gram 1dl(deciliter) = 0.1 liter to convert multiply 1000/10
(Micrograms per litre)/(gram molecular weight of solute) = (micromoles per litre).
3.6 (milligrams per deciliter) = 36 milligrams per liter.
2000 nanograms = 2 micrograms = 0.002 milligrams Hence to convert nanograms to milligrams divide by 1,000,000.
Each milligram per liter = 1.0 × 10-9 kilograms per cubic centimeter. So, multiply milligrams per liter by 1.0 x 10-9 to get kg per cubic cm.
One liter of water weighs exactly one kilogram. (This only true of water, oil, for example, weighs less.) There are 1000 ml (milliliters) in one liter, so one milliliter weighs one gram (not milligram!) and one gram is 1000 milligrams; therefore one milliliter is 1000 milligrams. There are then 0.07 milliliters in 70 milligrams.
