How to Convert Teragram to Petagram
To convert Tg to tonnes: multiply by 10⁶. To convert Tg to Gg: multiply by 1,000.
1 Tg = 10¹² g = 10⁹ kg = 10⁶ tonnes = 1 megatonne.
For example, 1 Teragram (Tg) = 0.001 Petagram (Pg).

About Teragram (Tg)
Definition
The teragram equals 10¹² grams or one million tonnes (one megatonne).
Mathematical Relationship
1 Tg = 10¹² g = 10⁹ kg = 10⁶ tonnes = 1 megatonne.
Conversion Formula
To convert Tg to tonnes: multiply by 10⁶. To convert Tg to Gg: multiply by 1,000.
Practical Applications
Global carbon budgets (~10,000 Tg C/year from fossil fuels), volcanic eruption plume masses.
Interesting Facts
Earth's atmosphere has a total mass of about 5.15 × 10⁶ Tg (5.15 × 10¹⁸ kg).
Common Mistakes
Confusing Tg with Pg (petagram): 1 Pg = 1,000 Tg. Climate papers use both — check carefully.
Educational Tips
Global CO₂ emissions ≈ 36,000 Tg/year (or 36 Pg/year). This is a key climate number to remember.
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.
