How to Convert Petagram to Dekagram
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+14 Dekagram (dag).

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 Dekagram (dag)
Definition
The dekagram (decagram) is a unit of mass equal to 10 grams.
Mathematical Relationship
1 dag = 10 g = 0.01 kg = 10,000 mg.
Conversion Formula
To convert dag to grams: multiply by 10. To convert dag to kg: divide by 100.
Practical Applications
Common at European delis and markets: '15 dag of cheese' means 150 g. Used in Austrian recipes.
Interesting Facts
In Austria and parts of Italy, the dekagram ('deka') is the default unit at deli counters — more common there than grams.
Common Mistakes
Not recognizing 'dag' or 'dkg' outside Europe. Converting: remember dag = 10 g, not 100 g.
Educational Tips
If you travel to Austria, 'ein Deka' at the deli means 10 grams. 10 Deka = 100 g.
