Ng and pg are both units of mass, but they are very different in size. A nanogram (ng) is one-billionth of a gram, while a picogram (pg) is one-trillionth of a gram. This means that a pg is 1,000 times smaller than a ng.
Ng and pg are often used to measure very small quantities of substances, such as drugs, hormones, and pollutants. For example, the amount of a drug in a person’s bloodstream may be measured in ng/mL.
Here is a table that summarizes the difference between ng and pg:
| Unit | Abbreviation | Definition |
|---|---|---|
| Nanogram | ng | One-billionth of a gram |
| Picogram | pg | One-trillionth of a gram |
Conversion between ng and pg
To convert ng to pg, you multiply by 1,000. To convert pg to ng, you divide by 1,000.
Examples
- 10 ng = 10,000 pg
- 100 pg = 0.1 ng
Applications of ng and pg

- Biology: Ng and pg are used to measure the amount of hormones and other biological molecules.
Conclusion
Ng and pg are both very small units of mass. They are often used to measure very small quantities of substances, such as drugs, hormones, and pollutants.
