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
-- take the number of parts per thousand-- multiply it by 1,000-- the answer is the number of parts per million
ppm means parts per million; percent basically means parts per hundred. Therefore, to convert from ppm to percent you should divide by 10,000.
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.
It's equal to 0.0000000015 percent. Think of this way: 15 parts per thousand is 15/1000 = 0.015 or 1.5 percent. 15 parts per million is 15/1E6 = 0.000015 or 0.0015 percent. 15 parts per billion is 15/1E9 = 0.000000015 or 0.0000015 percent. And 15 parts per trillion is 15/1E12 = 0.000000000015 or 0.0000000015 percent.
-- Take the number of percent. -- Multiply it by 10,000-- The answer is the number of parts per million. . 10 percent = 100,000 parts per million.
Parts per million is going to be ten thousand times more than parts per hundred.
Because the proportion of dissolved substances in seawater is such a small number, oceanographers typically express salinity in parts per thousand.
100 ppm = 0.1 parts per thousand and thus 0.01 parts per hundred = 0.01%
1 ppm = 0.0001 percent. Now go forth and convert.I'll do the first one for you: Zero ppm = Zero percent.
42 over 80 means 42 parts per 80. Percent means parts per 100. So, we need to convert the parts per 80 to parts per 100. Since 1.25 times 80 is 100, we can do this by multiplying the parts per 80 by 1.25. 1.25 times 42 is 52.5. Therefore, 42 over 80 equals 52.5 percent.
16 over 25 means 16 parts per 25. Percent means parts per 100. So, we need to convert the parts per 25 to parts per 100. Since 4 times 25 is 100, we can do this by multiplying the parts per 25 by 4. 4 times 16 is 64. Therefore, 16 over 25 equals 64 percent.
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
add 4 parts water per part solution
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.
It is per ten thousand.
On average, seawater in the world's oceans has a salinity of ~3.5%, or 35 parts per thousand.
The amount of the metal in question, in jewelry(gold in gold rings, silver in silver necklaces), is given in parts per thousand. So 417 stands for 417 parts the metal to 583 parts other metals. You can just divide it by 10 to convert it to percent, in this case 41,7 %
PARTS PER TRILLION or PARTS PER THOUSAND
38 parts per thousand
I is ot possible. You need TWO measures to convert to parts per million.
