Parts per million is a fraction with denominator 1,000,000. For example 5 parts per million means 5/1,000,000.

Percent is a fraction with denominator 100.

For example, 5 percent is 5/100.

So your goal is to convert a fraction with denominator 1,000,000 into a fraction with denominator 100.

Let's work an example:

5 parts per million means 5/1,000,000.

The rules of fractions allow us to multiply the numerator and denominator by the same number (except 0).

So multiply numerator and denominator by .0001 and we get

.0005/100.

Another word for .0005/100 is .0005 percent.

So the general rule is multiply the parts per million by .0001 or divide by 10,000 (same thing).

ppm means parts per million; percent basically means parts per hundred. Therefore, to convert from ppm to percent you should divide by 10,000.

I is ot possible. You need TWO measures to convert to parts per million.

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

1% is 10,000 parts per million.

1 ppm = 0.0001 percent. Now go forth and convert.I'll do the first one for you: Zero ppm = Zero percent.
