How to Convert Petagram to Decigram
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+16 Decigram (dg).
Petagram to Decigram — Common Values

| 1 | 1.000000e+16 |
| 2 | 2.000000e+16 |
| 5 | 5.000000e+16 |
| 10 | 1.000000e+17 |
| 25 | 2.500000e+17 |
| 50 | 5.000000e+17 |
| 100 | 1.000000e+18 |

| 1000 | 1.000000e+19 |
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 Decigram (dg)
Definition
The decigram is a unit of mass equal to one tenth of a gram (10⁻¹ g) or 100 milligrams.
Mathematical Relationship
1 dg = 0.1 g = 100 mg = 10 cg.
Conversion Formula
To convert dg to grams: divide by 10. To convert dg to mg: multiply by 100.
Practical Applications
Limited modern use. May appear in some European cooking recipes or educational worksheets.
Interesting Facts
The decigram was in wider use in the 19th century when the metric system was still establishing conventions.
Common Mistakes
Confusing dg (decigram) with dag (dekagram) — they differ by a factor of 100.
Educational Tips
Deci = one-tenth, deka = ten. They are opposite: dg = 0.1 g, dag = 10 g.
