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

∙ 11y agoIf 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.

∙ 10y agoSince 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.
To convert millimolar to milligrams per liter, you need to know the molar mass of the substance. Multiply the millimolar value by the molar mass, then multiply by 1000 to get milligrams. This value is equivalent to milligrams per liter as 1 milligram per liter is equal to 1 millimole per liter.
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 make a 10 ppm (parts per million) solution, you would need to add 10 grams of salt to 1,000,000 grams of solution (1,000,000 grams = 1,000 liters). Therefore, to make a 10 ppm solution in a smaller quantity, you would need to calculate the proportion of salt needed based on the desired volume of solution.
35 Grams of salt per liter
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.
-- take the number of parts per thousand-- multiply it by 1,000-- the answer is the number of parts per million

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%
To find the mass of NO2 in 1.00 liter of air, first convert the concentration of NO2 from ppm (parts per million) to grams per liter. Using the density of air, you can then calculate the mass of NO2 in 1.00 liter of air. In this case, 0.20 ppm of NO2 corresponds to 0.0000002 grams of NO2 per liter.
To convert parts per million (ppm) to grams per liter, you first need to convert ppm to milligrams per liter (since 1 ppm is equivalent to 1 mg/L) and then to grams per liter: 10 ppm = 10 mg/L Now, convert milligrams to grams: 10 mg = 0.01 grams Therefore, a liter of water with 10 ppm phosphorus would contain 0.01 grams of phosphorus.
