PPB
PPB stands for “parts per billion,” which is a unit used to express extremely low concentrations of a substance in a mixture. It indicates the number of parts of a specific substance in one billion (109) parts of the whole mixture.
PPM
PPM stands for “parts per million,” another unit used to express concentrations, where it represents the number of parts of a substance in one million (106) parts of the mixture. It’s commonly used to quantify small amounts of substances in various contexts like chemistry, environmental analysis, and industrial processes.
How to convert ppb to ppm
To convert from parts per billion (ppb) to parts per million (ppm), you can use the following conversion factor:
1 ppb = 0.001 ppm
Multiply the value in ppb by 0.001 to get the equivalent value in ppm. This conversion accounts for the difference in the number of parts in a billion compared to a million.

FAQs on ppb to ppm conversion
How do I convert ppb to ppm?
To convert PPB (parts per billion) to PPM (parts per million), divide the PPB value by 1000. This is because 1 PPM is equivalent to 1000 PPB.
What is 1 ppb equal to?
1 ppb is equal to 0.001 ppm. This means that for every billion parts of a mixture, there's 1 part of the substance.
Why does 1% equal 10,000 ppm?
The relationship between percentage and PPM is due to the different scales. Since 1% represents 1 part in 100, and 1 PPM represents 1 part in 1,000,000, 1% is 10,000 times larger than 1 PPM.
What is ppm vs ppb?
PPM (parts per million) and PPB (parts per billion) are both units for measuring concentration in a mixture. PPM signifies one part in a million, while PPB signifies one part in a billion.
Which is bigger, 1 ppb or 1 ppm?
1 ppm is larger than 1 ppb. This is because 1 ppm means 1 part in a million, whereas 1 ppb means 1 part in a billion. Thus, 1 ppm is 1000 times greater than 1 ppb.
How is ppm calculated?
PPM is calculated by dividing the number of parts of a substance by the total number of parts in the mixture and then multiplying by 1,000,000.
What is the value of 1 ppm?
1 ppm represents one part of a substance in a million parts of the mixture. In percentage terms, it's equivalent to 0.0001%.
