If you have 1 million parts of something 10 parts would be 10 parts per million. If you had 2 million parts of something 20 parts would be 10 parts per million.
-- take the number of parts per thousand-- multiply it by 1,000-- the answer is the number of parts per million
Well, honey, to convert micrograms per kilogram to parts per million, you need to multiply by 1,000. Why? Because there are 1,000 micrograms in a milligram, and 1,000,000 parts per million in a kilogram. So, it's just a matter of shifting those decimal places around to get the job done.
No. Even if that were milliliters to liters, it would still be parts per thousand.

50ppb is equal to 0.05ppm

To calculate parts per million (ppm) from molecular weight, you first need to know the mass of the substance in grams per mole. Then, you can use the formula: ppm = (mass of substance in grams / total mass of mixture in grams) * 10^6. This will give you the concentration of the substance in parts per million.
In chemistry, parts per million or ppm is defined as the number of part of a solute that is in one million parts of a solution. The formula to calculate ppm is to divide the mass of the solute in grams by the combined mass of the solvent and solute also in grams. This value is multiplied by 1,000,000 ppm.
1 ml of water weighs 1 gram, so if you are meaning microgram quantities, you would have parts per million. For example if you had 100 micrograms per ml, this would be the same as saying 100 grams per 1000 liters, which is the same ratio as 100 grams per million grams. Parts per million is expressed as ppm.
Xenon is a trace gas. Air is about .08 parts per million of Xenon. (For every million grams of air, there are .08 grams of xenon)
PPM-Parts Per Million: Number of grams of solute per 1 million grams of solution. ppm=[mass of solute/mass of solution]*10 to the 6th power&PPB-Parts Per Billion: Number of grams of solute per 1 billion grams of solution.ppb=[mass of solute/mass of solution]*10 to the 9th power.Hope this helps.
If you have 1 million parts of something 10 parts would be 10 parts per million. If you had 2 million parts of something 20 parts would be 10 parts per million.
parts per million = ppm
by "ppm" I assume you mean "parts per million". 30 percent means 30 per 100, and 1,000,000 (a million) divided by 100 is equal to 10,000. This is the ration between ppm and percent. 30x10,000 is equal to 300,000, so 30 percent is equal to 300,000 ppm
5% equates to 50,000 ppm
