ppm result: ppm


What is ppb to ppm conversion

To convert parts per billion (ppb) to parts per million (ppm), you need to divide the ppb value by 1,000.

The formula for the conversion is as follows:

ppm = ppb / 1,000

For example, let's say you have a concentration of 500 ppb and you want to convert it to ppm.

ppm = 500 ppb / 1,000

ppm = 0.5 ppm

So, 500 ppb is equal to 0.5 ppm.

When converting between different parts-per notations, you are essentially multiplying or dividing by powers of 10. In this case, dividing ppb by 1,000 converts it to ppm.

How to convert ppb to ppm

ppm and ppb are defined as:

1ppm = 1/106 = 10-6

1ppb = 1/109 = 10-9


1ppm = 1000ppb

The number of parts-per million xppm is equal to the number of parts-per billion xppb divided by 1000:

xppm = xppb / 1000

Example: 7000ppb is equal to 7ppm:

xppm = 7000ppb / 1000 = 7ppm
