1 mg per litre is 1 mg per kilogram, but only if you think of pure water. 1 litre of pure water weighs 1 kilogram.

Don't, you can't.

You cannot. The milligram is a unit of weight and the litre a unit of volume. In the case of water only a litre happens to weigh a kilogram and therefore a milligram of water is 0.1 % of a kilogram and 0.1 % of a litre.

to convert milligram per liter to percentage, multiply by 10000 Explanation one milligram per liter is 1 ppm 10000 ppm is 1 percentage

Divide by 1000.

Given that a liter of water does weight about a kilogram, there would be a million milligrams of water per liter, so yes, one milligram per liter does work out to be one part per million (ppm).

ppm = part per million; vpm = volume per million 1 ppm = 1 milligram/kilogram or 1 milligram/liter

Simple. Do nothing since they are equivalent.

There are 1000 micrograms in a milligram. Therefore you have to divide by 1000. The litres are the same units so you don't have to touch the calculation at all after that.

Divide the density in kilograms per liter by the volume in liters

One litre is equal to one Kilogram of H2O. Therefore, in consideration to solutes in water, a milligram per litre is equal to a milligram per kilogram. 1 kilogram = 1000 grams. 1 gram = 1000 milligrams. Therefore 1 kilogram = 1000x1000 = 1 000 000 milligrams. Back to the first statement, substituting 1 000 000 milligrams for kilogram: a milligram per litre is equal to a milligram per 1 000 000 milligrams, which is one part per million. Cheers, Anthony F.

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.

1 milligram = 1,000 micrograms -- Take the number of micrograms per liter -- Divide by 1,000 -- The answer is the number of milligrams per liter. Example: 6 micrograms per liter = 0.006 milligrams per liter.

One milligram per kilogram IS one part per million: There are 1,000 milligrams in one gram and 1,000 grams in one kilogram. 1,000 mg = 1 g 1,000 g = 1 Kg 1,000 x 1,000 = 1,000,000

1 milligram per litre is 0.001 grams per litre. 1 gram per litre is 1000 milligrams per litre.

Divide by ten. e.g. 200 mg/L = 20%

1 milligram = 10-6 kilograms So 3.34 milligrams in 1 kilogram = 3.34*10-6 in 1 As a percentage, this is 100*3.34*10-6 = 3.34*10-4

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.

Divide by a million... 1000 for the milligram to gram conversion, and 1000 for the liter to milliliter conversion. This may help: mg / l * (1 g / 1000 mg) * (1 l / 1000 ml) = g / ml.

To convert this you need to divide 1mg by the molecular weight of the compound in question. When you do this, the volume is the same, so there is no further adjustment needed.

If it has the same density as water, the conversion is direct, just multiply the parts per thousand by 1,000. Otherwise, you need to convert the weight in milligrams to volume in milliliters. It takes 1,000,000 milligrams of water to equal a liter.

If you have 1 gm per liter, then you would have 1000 milligrams per 1000 milliliters. You would then reduce this to be 1 milligram per milliliter. So, the answer is that the ratio would stay the same.

1 nanogram per liter = 1.0 × 10-6 mg/L

In order to convert a microliter per liter to a mililiter per liter, just divide by 1,000.

The difference between a milligram and a kilogram is quantity. With one gram as the basic unit of measure, one milligram is one one thousandth (1/1000) of a gram. One kilogram is one thousand (1000) grams. Therefore one kilogram is one million milligrams (1000 milligrams per gram times 1000 grams per kilogram).

1 milligram per liter = 0.000121703815 troy ounces per US gallon. So, multiply the number of mg per liter by 0.000121703815 to get troy ounces per US gallon. Example, 500 (milligrams per liter) x 0.000121703815 = 0.0608519075 troy ounces per US gallon.
