How to Convert ppb to mg/kg
To convert from parts per billion (ppb) to milligrams per kilogram (mg/kg), you can use the following conversion:
1 ppb is equal to 1 microgram per kilogram (µg/kg).
Since 1 milligram (mg) equals 1000 micrograms (µg), we can say that:
1 ppb = 0.001 mg/kg
Therefore, to convert a value from ppb to mg/kg, simply multiply the ppb value by 0.001.
Example:
If you have a concentration of 2500 ppb, the equivalent in mg/kg would be:
2500 ppb × 0.001 = 2.5 mg/kg
This conversion is commonly used in fields like food safety, environmental testing, and chemical analysis, where accurate measurements of very small concentrations are important.

FAQs
Q: What does ppb stand for?
A: PPB stands for “parts per billion.” It is a unit used to express very small concentrations of substances, especially in environmental and chemical measurements.
Q: What does mg/kg mean?
A: MG/KG stands for “milligrams per kilogram.” It is a measurement of the amount of a substance (in mg) per unit mass of another substance (in kg), commonly used for food, soil, and chemical testing.
Q: Is 1 ppb equal to 0.001 mg/kg?
A: Yes, as long as you’re measuring within the same medium (like solids or liquids), 1 ppb is equivalent to 0.001 mg/kg.
Q: When should I use ppb instead of mg/kg?
A: Use ppb when you need to express very small concentrations in a way that avoids decimals, and mg/kg when a metric system unit is preferred or required by standards.
Q: Can I convert mg/kg to ppb as well?
A: Yes, to convert from mg/kg to ppb, multiply the mg/kg value by 1000.
