How to Convert Petagram to Nanogram
To convert Pg to tonnes: multiply by 10⁹. To convert Pg to Tg: multiply by 1,000.
1 Pg = 10¹⁵ g = 10¹² kg = 10⁹ tonnes = 1 gigatonne.
For example, 1 Petagram (Pg) = 1.000000e+24 Nanogram (ng).
Petagram to Nanogram — Common Values

| 10 | 1.000000e+25 |
| 25 | 2.500000e+25 |
| 50 | 5.000000e+25 |
| 100 | 1.000000e+26 |
| 500 | 5.000000e+26 |
| 1000 | 1.000000e+27 |
About Petagram (Pg)
Definition
The petagram equals 10¹⁵ grams or one billion tonnes (one gigatonne).
Mathematical Relationship
1 Pg = 10¹⁵ g = 10¹² kg = 10⁹ tonnes = 1 gigatonne.
Conversion Formula
To convert Pg to tonnes: multiply by 10⁹. To convert Pg to Tg: multiply by 1,000.
Practical Applications
Global carbon budgets: about 10 Pg of carbon are emitted annually from fossil fuels.
Interesting Facts
The total mass of all life on Earth is estimated at about 550 Pg of carbon.
Common Mistakes
Confusing Pg (petagram = 10¹⁵ g) with PB (petabyte). In mass contexts, P = peta = 10¹⁵.
Educational Tips
1 Pg C = 1 gigatonne of carbon. Annual human CO₂ emissions are about 10 Pg C — a key climate figure.
About Nanogram (ng)
Definition
The nanogram is a unit of mass equal to 10⁻⁹ grams or 10⁻¹² kilograms — one billionth of a gram.
Mathematical Relationship
1 ng = 10⁻⁹ g = 10⁻¹² kg = 1,000 pg = 0.001 µg.
Conversion Formula
To convert ng to µg: divide by 1,000. To convert ng to grams: multiply by 10⁻⁹.
Practical Applications
Drug dosing in ng/mL (blood levels), pesticide residue testing, and pollution monitoring (e.g., dioxin levels).
Interesting Facts
Many potent drugs are effective at blood concentrations of just a few ng/mL — a testament to how sensitive your body is.
Common Mistakes
Confusing ng/mL with µg/mL — a factor of 1,000 difference that can cause dangerous dosing errors in medicine.
Educational Tips
Drug levels in blood are often in ng/mL — if someone says 'nanograms per milliliter', think trace-level drug monitoring.
