How to Convert Petagram to Deuteron Mass
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) = 2.990803e+38 Deuteron Mass (md).

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 Deuteron Mass (md)
Definition
The deuteron mass is the mass of a deuterium nucleus (one proton + one neutron), approximately 3.344 × 10⁻²⁷ kilograms.
Mathematical Relationship
md < mp + mn by 2.224 MeV/c² (the binding energy). This 'mass defect' represents nuclear binding energy.
Conversion Formula
To convert deuteron masses to kg: multiply by 3.3435837724 × 10⁻²⁷.
Practical Applications
Fusion energy research (deuterium-tritium and deuterium-deuterium reactions), NMR/MRI, and neutron production targets.
Interesting Facts
The deuteron's binding energy (2.224 MeV) is quite small, making it the most weakly bound stable nucleus.
Common Mistakes
Assuming md = mp + mn exactly — the mass defect (binding energy) makes the deuteron slightly lighter than the sum.
Educational Tips
The deuteron is the simplest nucleus with more than one nucleon. Its binding energy (2.224 MeV) is E=mc² in action.
