parts per billion to parts per million
Please provide values below to convert parts per billion [ppb] to parts per million [ppm], or change ↔.
parts per billion [ppb]
Definition: Parts per billion (ppb) is a unit used to describe extremely dilute concentrations of substances, representing one part of solute per billion parts of solution.
Historyandorigin: Parts per billion is an extension of the ppm concept, used when concentrations are too small to be expressed in ppm.
CurrentUse: It is often used in environmental monitoring, especially for trace pollutants or substances like pesticides, heavy metals, or gases in the air.
funfact: 1 ppb is equivalent to 1 microgram of solute in one liter of water—great for measuring incredibly low concentrations like toxins or pollutants!
parts per million [ppm]
Definition: Parts per million (ppm) is a unit used to describe very dilute concentrations of substances, representing one part of solute per million parts of solution.
Historyandorigin: The term parts per million became popular in the 20th century to quantify trace amounts of pollutants and other substances in environmental science.
CurrentUse: It is commonly used in environmental science, medicine, and chemistry to express concentrations of pollutants, chemicals, and gases in air or water.
funfact: 1 ppm means that for every million parts of a substance, only one part is the solute—equivalent to 1 milligram per liter in water!

How to Convert parts per billion to parts per million
1 parts per billion [ppb] = 0.001 parts per million [ppm]
1 parts per million [ppm] = 1000 parts per billion [ppb]
we use cross multiplication method
parts per billion [ppb] → parts per million [ppm]
1 → 0.001
1.5 → ?( suppose x)
=>1.5*0.001=1*x
by simplifying
x=0.0015
