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
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.
Since 1000 ml equal to one liter the number of grams will become parts per thosand. For example if there are 98 grams of a solute in one liter of water, the solution may be called as 98 parts per thosand.
1000 ppm = 1 ppb I think equation to convert ppm to ppb is: 1 ppm = 1000 ppb, or 1 ppb = 1/1000 ppm * * * * * Wrong way around, I am afraid. 1000 parts per billion is 1 ppm. To convert ppb to ppm divide by 1000.
There are no units of concentration. Concentration is written as density, which requires a mass measurement, and a volume measurement. The standard units for this is grams per liter.
10 g is 10,000 mg and in 1 liter that would be 10,000 ppm. You need to have a volume in order to express the mass as ppm. In other words, 10 g NaCl cannot be expressed as parts per million unless you have the volume that it is in. If it's in a liter, then you will have 10,000 ppm.
Ppm is part per million, a microgram is one millionth of a gram, a litre of water approximates to 1000g. 1300 micrograms is 1.3 milligrams. One milligram is one thousandth of a gram, as one litre is one thousand grams, 1mg/L is 1ppm ( 1 000 X 1 000 = 1 000 000), so 1.3mg/L is 1.3ppm.
To convert milligrams per liter (mg/l) to milligrams, you need a volume of the substance in question, and then you'll just multiply the two together. In "math speak" here, ( mg/liter ) times ( liters ) equal mg. See where we're going? The first unit is a density, which is weight (mass) per unit of volume. If you have a density of a material and you have a stated volume of the material, you can multiply them together to find out how much mass of that substance you have. If you have oxygen, its density is about 1.429 grams/ liter at STP. That converts to 1429 mg/liter. And if you have, say, 10 liters of the oxygen, you'll have 10 liters x 1429 mg/liter = 14,290 mg of oxygen.
35 Grams of salt per liter
-- take the number of parts per thousand-- multiply it by 1,000-- the answer is the number of parts per million
3.3%
80 parts per thousand (ppt) means there is 80 grams (g) of NaCl (salt) per 1000 grams of water. 1L is approximately 1000 grams of water; it can vary slightly depending on the temperature.
990/1000
mass into parts per hundred ..... can't be done.
No. Even if that were milliliters to liters, it would still be parts per thousand.
Move the decimal point one place to the left. Percent literally means per hundred, so 1 part per thousand is 0.1%, 10 parts per thousand is 1%, 100 parts per thousand is 10%, and 1000 parts per thousand is 100% or a whole.
1% equals 1 part per hundred, so it also equals 10 parts per thousand, 100 parts per ten thousand, 1000 parts per hundred thousand or 10000 parts per million
35/1000 = 3.5/100 = 3.5%
